Cleavage (breasts)

For other uses, see Cleavage.

A woman's cleavage

Cleavage is the narrow depression or hollow between human breasts, the top portion of which may be accentuated by clothing such as a low-cut neckline that exposes the division. Joseph Breen, head of the U.S. Production Code Administration (PCA), coined the term in its current meaning when evaluating the 1941 Jane Russell starrer The Outlaw, and first covered by Time magazine in August 5, 1946. It is most commonly used in the parlance of Western female fashion to refer to necklines that reveals or emphasizes décolletage or display of the upper breast area.

In many cultures, though not all, men typically derive erotic pleasure from a cleavage display. This tendency has been attributed to many reasons including evolutionary psychology, a patriarchal revolution, dissociation from brestfeeding and kundalini shakti. Since at least the 15th century, women in the Western world have used their cleavage to flirt, attract, make gender statements, and assert power. In several parts of the world, the advent of Christianity and Islam saw sharp decline in the amount of cleavage which was considered socially acceptable. In many cultures today, cleavage exposure is considered unwelcome or is banned legally; in some areas like European beaches and among many indigenous peoples across the world, it is ignored; conversely, even in the West it is often discouraged in daywear or in public spaces. In some cases, exposed cleavage can be a target for unwanted voyeuristic photography or sexual harassment.

Cleavage revealing clothes started becoming popular in the Christian West as it came out of the Early Middle Ages and enjoyed significant prevalence during Mid-Tang-era China, Elizabethan era England, and France over many centuries, particularly after the French Revolution. But in Victorian era England and during the flapper period of Western fashion it was suppressed. Cleavage came vigorously back to Western fashion in 1950s, particularly through Hollywood celebrities and lingerie brands. The consequent fascination with the cleavage was most prominent in the US, and countries heavily influenced by the US. With the advent of push-up and underwired bras that replaced corsets of yesteryears the cleavage fascination was propelled by these lingerie manufacturers. By the time of the COVID pandemic, dramatization of the cleavage started to lose popularity along with the big lingerie brands. At the same time cleavage was sometimes replaced with other types of presentation of clothed breasts, like sideboobs and underboobs.

Many women, both cisgendered and transgendered, enhances their cleavage by use of devices like brassières, falsies and corsetry, as well as surgical breast augmentation using saline or silicone implants and hormone therapy. Workout, yoga, skin care, make up, jewelry, tatoo and piercings are also used to embellish the cleavage. Male cleavage (also called heavage), accentuated by low necklines or unbuttoned shirts, is a movie trend in Hollywood and Bollywood. Some men also groom their chests. Prominent cleavage in men — also known as "man boobs" or "moobs" — may be due to gynecomastia, a disorder that causes male breast enlargement.

Etymology

Jane Russell in The Outlaw (1941). Director Howard Hughes' overemphasizing of her cleavage prompted the MPAA to take actions against the film and use the term "cleavage" in association with breasts. Hughes and Russell are considered pioneers of exaggerated cleavage in movies. For the film Hughes designed a prototype for an underwire bra to give Russell "five and one-quarter inches" long cleavage.

The word "cleavage" was first used in early 19th century in geology and mineralogy to mean the tendency of crystals, minerals and rocks to split along definite planes. By the mid-19th century, it was generally used to mean splitting along a line of division into two or more parts. In the 1940s, Joseph Breen, head of the U.S. Production Code Administration (PCA), applied the term to breasts in reference to actor Jane Russell's costumes and poses in the 1941 movie The Outlaw. The term was also applied in the evaluation of the British films The Wicked Lady (1945), starring Margaret Lockwood and Patricia Roc; Bedelia (1946), also starring Lockwood; and Pink String and Sealing Wax (1945), starring Googie Withers. This use of the term was first covered in a Time article titled "Cleavage & the Code" in August 5, 1946, as a "Johnston Office (the popular name for Motion Picture Association of America (MPAA) office at the time) trade term for the shadowed depression dividing an actress' bosom into two distinct sections." The word "cleavage" is made of the root verb "cleave" (to split, from Old English clifian and Middle English clevien ("cleft" in past tense) and the suffix age (meaning "the state of" or "the act of").

While the division of the breasts is a cleavage, the opening of a person's garments to make the division visible is called a décolletage, a French word that is derived from décolleter meaning "to reveal the neck". The term was first used in English literature before 1831 and was the preferred term among educated people in the English-speaking world before cleavage became the popular term.

Décolletage (or décolleté in adjectival form) refers to the upper part of the female torso, consisting of the neck, shoulders, back and chest, which is exposed by the neckline, the edge of a dress or shirt that goes around the neck, especially at the front of a woman's garment. The neckline and collar are often the most attention-grabbing parts of a garment, effected by bright or contrasting colors, or by décolletage. The term is most commonly applied to a neckline that reveals or emphasizes cleavage and is measured as extending about two hand-breadths from the base of the neck down; both in the front and the back. In anatomical terms, the cleft in the human body between the breasts is known as the intermammary cleft or intermammary sulcus.

Typology

According to a paper by British surgeon Muhammad Adil Abbas Khan et al, there are eight common types of cleavage from a frontal and a bird's eye view.

Image	Name	Description
Anteroposterior or frontal view
noborder	Cocktail Glass	In the cocktail glass appearance, the breasts are in close proximity and there is no space between them in the inferior half of the cleavage. The superior part of the cleavage acutely curves away from the breasts in a relatively linear fashion leaving a wider, exposed region of the cleavage.
noborder noborder	Champagne Glass	In the champagne glass appearance, the breasts are in close proximity but are not in contact, leaving a visible region between the breasts along the length of the cleavage. The gap in the superior part increases significantly and the contours bend away from the midline and the gap in the inferior half remains short and constant. The result is a wider cleavage in the superior half than the cocktail glass cleavage.
noborder	Hourglass	In the hourglass appearance, the medial contours of the breast almost touches at a simple point of contact. Compared to the cocktail glass and champagne glass appearance, breasts with an hourglass cleavages have less proximity between them. The gap of the cleavage is minimum at the midpoint between superior and inferior poles, while the distance increases somewhat symmetrically towards both these ends.
noborder	Highball Glass	In the highball glass appearance, the breasts are a significant distance from each other. The gap of the cleavage stays significantly constant through its length.
Craniocaudal or bird’s eye view
noborder	Cocktail Glass	In the cocktail glass appearance, the breasts are in close proximity to each other and meet at some point in the cleavage, leaving no visible gaps between them. The breasts then curve anterio-laterally in a relatively linear manner towards the areolae.
File:Cleavage classification B - Goblet Glass.png	Goblet Glass	In the goblet glass appearance, the cleavage is a result of the close proximity of the breasts to each other without a point of contact between them. A goblet glass cleavage forms a curved shape in the center of the intermammary cleft, which then curves antero-laterally towards the areolae. The curves are more pronounced than the more linear appearance of the cocktail glass cleavage .
noborder	Margarita Glass	In the margarita glass appearance, the cleavage is similar to both the cocktail glass and goblet glass cleavages but the gap of the intermammary cleft is wider while the medial breast is curvier and tapers antero-laterally more acutely.
noborder	Tumbler Glass	In the tumbler glass appearance, the breasts are further apart. The medial curves of the breasts descend sharply posteromedially and hence do not extend further towards the midline. This leaves a flat region in the cleavage, representing the region superficial to the sternum that lacks breast tissue. Instead of being curved, the cleavage has a rectangular or boxy appearance.

In many cultures, men typically find female breasts attractive. In these cultures, women use décolletage that exposes cleavage to enhance their physical and sexual attractiveness, and to improve their sense of femininity. Display of cleavage with a low neckline is often regarded as a form of flirting or seduction, as much as for its aesthetic or erotic effect. According to Kinsey Reports, most men derive erotic pleasure from seeing a woman's cleavage. When designing costumes, creating shapes that draw attention to the face or the chest helps distract the gaze from body parts that are considered less desirable.

Though it was observed by the United States federal courts that definition of "anal cleft or cleavage" (i.e. Intergluteal cleft) and "cleavage of the female breast" are very imprecise, Rabbi Aha b. Raba (circa 5th century) and Nathan the Babylonian (circa 2nd century) had measured the appropriate size of the cleavage as "of one hand-breadth between a woman's breasts".

The amount of cleavage exposure that is acceptable in public differs significantly between cultures and societies. In contemporary Western society, the extent to which a woman may expose her breasts depends on the social and cultural context. Among respectable women, displaying any part of the female breast may be considered inappropriate and may be prohibited in some settings, such as workplaces, churches, and schools, while in other spaces, such as parties, beaches and pools, it may be permissible to showi as much cleavage as possible. Art historian James Laver noted the changing standards of cleavage are mostly applicable to evening wear rather than to day wear. The exposure of nipples and areolae is almost always considered immodest and in some instances is viewed as indecent behavior.

The fascination with female breasts and cleavage is widespread but not universal; it is more prevalent in Western and Westernized cultures, particularly those in the U.S. and countries that are heavily influenced by the U.S. Many people in Western culture, both male and female, consider breasts to be an important female secondary sex characteristic and as aspect of femininity. The flaunting of cleavage became an aggressive statement of gender. Films like Erin Brockovich, in which Julia Roberts was required to wear a silicone gel-filled bra to increase her cleavage, demonstrated cleavage as a woman's right and an application of feminine attributes as "a source of power".

In some cultures, for example in African communities, it is not unusual to see uncovered breasts, which are not considered titillating. According to Valerie Steele, director of Fashion Institute of Technology, "For centuries (even in the judeo-Christian and Islamic worlds), the sight of a woman nursing was accepted as normal. This factor contributed to the fairly rapid acceptance of dresses with low necklines, which were introduced in the fifteenth century." Since emerging in the Christian West, the early décolleté dresses—which were termed by French court historian Jean Froissart as "the smile of the bustline"—had increasingly plunging necklines because the Renaissance celebrated the beauty of the unclothed human body. Moralists, who blamed any number of chest illness on bare cleavage, were shocked by the development.

"I interviewed a young anthropologist working with women in Mali, a country in Africa where women go around with bare breasts. They're always feeding their babies. And when she told them that in our culture men are fascinated with breasts there was an instant of shock. The women burst out laughing. They laughed so hard, they fell on the floor. They said, 'You mean, men act like babies?'"

Carolyn Latteier, All about breasts

Women's traditional clothing in India generally exposes more midriff than cleavage but they often wear saris and cholis (blouses) in a way "the entire back, including the shoulders remain bare; in the front often the cleavage between breasts is exposed and the entire region between the breasts and navel remains uncovered". Gagra choli, a dress taken as very chaste in India, also exposes significant amount of midriff and cleavage. Cholis customized for Bollywood movies has particularly deep décolletage. Women of the Bishnoi people wear kanchli blouses with very deep necklines that are embellished with frills and bells to draw attention to their cleavage. Women of Ahir, Gadariya and Chamar communities wear Angiya, a small, bikini-like top that is tied at the back with a string, often with the front open enough to show deep cleavage. During the Middle Ages and up to the Renaissance, a woman's stomach was often the central symbol of her sexuality for centuries, rather than the breasts.

In Islam, the Quran states, "Let them draw their khimar (shawl, headscarf or veil) over their juyub (breast-line / cleavage)". The ayat (verse) refers to women's clothing that was, at the time the verse was written, worn parted at the front to expose the breasts. The verse was later interpreted as requiring the complete covering of women's bodies. In the early 21st century Muslim world, there is a popular consensus that modesty requires coverage of any cleavage. As of 2011, women in Saudi Arabia and Afghanistan were required to completely cover their bodies; Iranian law required the wearing of a chador (over-cloak) or a hijab (head scarf), and in Egypt, the exposure of cleavage in the media was considered to be nudity. Décolleté dresses were sighted in modern Palestine region only after establishment of the Jewish state of Israel.

During adolescence, some girls become obsessed with breast shape and cleavage while some others try to resist the growth of their breasts during puberty by binding down their breasts, wearing loose clothes that disguise them or adopting a hunched or stooped posture. A study found girls whose breasts develop early may be ashamed and embarrassed because of unwanted stares. There is historical evidence some cultures, including classical antiquity, strongly discouraged cleavage or any hint of a bosom. Early English Puritans used a tight bodice to completely flatten breasts while 17th-century Spaniards put lead plates across the chests of pubescent girls to prevent their bosoms from developing.

"Downblouse" is a cultural phenomenon of voyeurism, fetishism and sexual offense that involves looking down a woman's dress or top to observe or photograph her cleavage or breasts. The phenomenon emerged in the 21st century, atthough the term has been used in English since 1994. The popularity of covert downblouse and upskirt photography increased with the proliferation of camera phones since 2000. NASUWT, a UK teachers' union, reported an upward trend of such pictures at schools in 2018.

Many of these covertly taken pictures are uploaded to websites, including pornographic websites like Pornhub, XVideos and Xhamster, as well as subreddits like r/creepshots. Some websites host tutorials on taking downblouse and upskirt pictures. As early as 2004, Google listed about four million websites that were tagged with "upskirt" and "downblouse". Some jurisdictions, including the UK Germany, and as a number of American and Australian states, have statutes that prohibit such covert photography. In the UK, people who take such pictures and post them online can be listed on the sex offender registry, and in Japan the government has pressured mobile phone manufacturers to make their phones produce a warning sound whenever such pictures are taken. These types of offenses "largely [go] unreported" and, according to Maria Miller, chair of the Women and Equalities Committee, the legal provisions are inadequate.

Theories

Fertility ratings as a function of breast size and intermammary cleft distance

Hypothetically, non-paraphilic sexual attraction to breasts is a result of their function as a secondary sex characteristic. The breasts play roles in both sexual pleasure and reproduction. According to the DSM-5, sexual attraction to breasts is normal unless it is highly atypical and is therefore a form of partialism. According to sociologist Anthony Joseph Paul Cortese, the cleavage area between the breasts is "perhaps the epicentre" of display of female sexual attractiveness and stimulation of male sexual interest. According to social historian David Kunzle, waist confinement and décolletage are the primary sexualization devices of Western costume. According to music writer Ben Watson in Art, Class and Cleavage (1998), the deployment of the cleavage punctures through art's "spiritual pretensions" and alerts us to the bodily roots of all culture.

Vincenz Czerny, one of the early surgeons to do a breast surgery, believed the aesthetics of cleavage to be a sign of symmetry and hence beauty. A study published in 2020 found intermammary distance (IMD) or cleavage gap)is one of the major influences on people's perception about a woman's fertility, health and age. Another study found women who display cleavage are more often identified as "voluptuous" than women who do not. From an aesthetic perspective, a greater width-per-volume of the round shape of the breasts produces a satisfactory cleavage and changes the angles to a more feminine contour. From a surgical perspective, the recommended intermammary distance is between 2 and 3 centimetres (0.79 and 1.18 in).

Swelling of the anterior is a sign of mating-readiness in most ape species. Among humans the upright posture reduces visibility of the buttocks, while the breasts are significantly enlarged. This evolution may have caused a shift in signs of mating-readiness and attractiveness from swagging buttocks to pendulous breasts.

Zoologist and ethologist Desmond Morris theorizes cleavage is a sexual signal that imitates the cleft between the buttocks. Evolutionary psychologists theorize humans' permanently enlarged breasts, in contrast to other primates' breasts—which only become enlarged during ovulation—allowed females to "solicit male attention and investment even when they are not really fertile". Hypothetically, with evolutionary changes, the sign of mating-readiness and attractiveness in females has shifted from the swagging swelled anterior—a sign of mating-readiness in other primates—to the pendulous shape of breasts and cleavage of humans, whose upright posture reduces the visibility of the buttocks. Hence breast and buttock cleavages, sharing a similarity between their appearances, are considered to be erotic in many societies.

American anthropologist Clellan S. Ford and ethologist Frank A. Beach said in their book 1951 book Patterns of Sexual Behavior only 13 of 130 cultures in a cross-cultural survey perceived female breasts as sexually attractive. Author Elizabeth Gould Davis said breasts, along with phalluses, were revered by the women of Catal Huyuk as instruments of motherhood but after a "patriarchal revolution", when men had appropriated both phallus worship and "the breast fetish" for themselves, these organs "acquired the erotic significance with which they are now endowed".

In Alexandre Guillaume Mouslier de Moissy's 1771 play La Vraie Mère ("The True Mother"), the title character rebukes her husband for treating her as an object for his sexual gratification; "Are your senses so gross as to look on these breasts—the respectable treasures of nature—as merely an embellishment, destined to ornament the chest of women?". In the 19th century, biologists and philosophers like Carl Linnaeus and Jean-Jacques Rousseau attempted to popularize the idea of breastfeeding of one's own children as natural and fashionable.

The mandala (diagram) for anahata chakra, the yogic heart that lies at the depression in the sternum between the nipples

From a cultural perspective, men are not as much biologically drawn to breasts as they are trained to find them erotic. According to author Marilyn Yalom in A History of the Breast, around these times, male thinkers decided a nursing mother’s breasts were both erotic and a source of nourishment for future citizens of the nation. According to psychologist Richard D. McAnulty, when breasts are hypersexualized, they is not perceived as a body part to breastfeed infants. Therefore exposure of the breast, such as in public breastfeeding, is considered embarrassing. Science journalist Natalie Angier shifts from using the term "functional" to using the term "maternal" to describe the "non-aesthetic breast" in her book Woman: An Intimate Geography (1999). In the same book, she argues human fascination with full cleavage may be a result of our fascination with round objects and attraction towards well-defined curves.

The cleavage area is special in Ayurvedic and Yogic philosophy as the fourth chakra' or anahata chakra (meaning "unstruck" in Sanskrit, the heart chakra) supposedly lies at the level of the depression in the sternum. The astral anahata chakra supposedly lies between the breasts, just inside the front of the chest level with the nipples. According to Yogashikha Upanishad, the sacred text on yoga, 101 nadis (energy channels) connect the anahata chakra with the rest of the body, including ida, pingala and shushumna, the three major nadis.

According to yoga philosophy, the kundalini shakti (the feminine energy) rises from the muladhara chakra (root chakra) in the pelvic area to reach the cleavage area, a fundamental center for growth of a human being, where at the anahata chakra it is expressed as love, hate and fear. In the cleavage area, according to yoga philosophy, lies the yogic heart of a person, not the heart of flesh, that serves as the bridge between the three lower chakras and the three higher chakras, and when the kundalini remains in the Anahata Chakra, a person is inclined to good and noble desires, thoughts and acts.

History

Main article: History of the cleavage

Ancient

Princess Nofret (27th century BCE) of the Fourth Dynasty of Egypt

Minoan snake goddess (17th century BCE)

In 2600 BCE, princess Nofret of the Fourth Dynasty of Egypt was depicted wearing a V-neck gown with a plunging neckline that exposed ample cleavage that was further emphasized by an elaborate necklace and prominently protruding nipples.

In ancient Minoan culture, women wore clothes that complemented slim waists and full breasts. One of the better-known features of ancient Minoan fashion is breast exposure; women wore tops that could be arranged to completely cover or expose their breasts, with bodices to accentuate their cleavage. In 1600 BCE, snake goddess figurines with open dress-fronts revealing entire breasts, were sculpted in Minos. By that time, Cretan women in Knossos were wearing ornamental fitted bodices with open cleavage, sometimes with a peplum. Another set of Minoan figurines from 1500 BCE show women in bare-bosomed corsets.

Ancient Greek women adorned their cleavage with a long pendant necklace called a kathema. The ancient Greek goddess Hera is described in the Iliad to have worn something like an early version of a push-up bra festooned with "brooches of gold" and "a hundred tassels" to increase her cleavage to divert Zeus from the Trojan War. Women in Greek and Roman civilizations had at times used breastbands like taenia in Rome to enhance smaller busts but more often, women of the masculine Greco-Roman world, where unisex clothes were often preferred, used breastbands like apodesmes in Greece, and fascia or mamillare in Rome to suppress their breasts. Among these mamillare was a particularly strict leather corset for suppressing women with big busts.

A silver coin that was found in South Arabia in the 3rd century BCE shows a buxom foreign ruler with much décolletage and an elaborate coiffure. Rabbi Aha b. Raba (circa 5th century) and Nathan the Babylonian (circa 2nd century) measured the appropriate size of the cleavage as "of one hand-breadth between a woman's breasts".

Medieval

Courtiers in China during Tang dynasty(circa 706), when the décolletage was quite liberal. 2014 Chinese TV series The Empress of China was briefly pulled off-air for showing the abundance of cleavage in Tang courts.

During the Tang dynasty (7th to 9th centuries), women in China were increasingly freer than before and by the mid-Tang, their décolleté dresses became quite liberated. The Tang women inherited the traditional ruqun gown and modified it by opening up the collar to expose their cleavage, which had previously been unimaginable. Rather than the conservative garments worn by earlier Chinese women, women of the Tang era deliberately emphasized their cleavage. The popular style of the era was long gowns of soft fabrics that were cut with a pronounced décolletage and very wide sleeves, or a décolleté knee-length gown that was worn over a skirt.

Between the 11th and 16th centuries, the prevailing décolleté clothes of women of Punjab, Gujarat and Rajasthan in India were replaced with covered bosoms and long veils as the region increasingly came under foreign control. During this period, elaborate, opulent courtly dresses with wide décolletage became popular in the Italian maritime states Venice, Genoa and Florence.

Until the 12th century, the Christian West was not cleavage friendly but beginning in France, a change in attitude occurred by the 14th century, when necklines were lowered, clothes were tightened and breasts were once again flaunted. Décolleté gowns were introduced in the 15th century. In a breast-rating system that was invented at the time, the highest rating was given to breasts that were "small, white, round like apples, hard, firm, and wide apart".

Women started squeezing the breasts and applying make up to make their cleavage more attractive; cleavage was termed the "smile of the bustline" by contemporaneous Belgian chronicler Jean Froissart. A contemporaneous French courtesy manual La Clef d‘Amors advised, "If you have a beautiful chest and a beautiful neck do not cover them up but your dress should be low cut so that everyone can gaze and gape after them". Contemporaneous poet Eustache Deschamps advised "a wide-open neckline and a tight dress with slits through which the breasts and the throat could be more visible". Sewing two pouches into one’s dress "into which the breasts are squeezed so that the nipples arc thrust upwards" was suggested.

The French Catholic Church, however, tried to discourage the flaunting of cleavage. It mandated the cleavage, which it referred to as "the gates of hell", and the opening on woman's bodices be laced. French priest Oliver Maillard said women who exposed their breasts would be "strung up in hell by their utters". Monarchs like Charles VII of France ignored the church. It was common for women in his court to wear bodices through which their breasts, cleavage and nipples could be seen. In 1450, Agnès Sorel, mistress to Charles VII, started a fashion trend when she wore deep, low, square décolleté gowns with fully bared breasts in the French court.

Early modern

Across Europe, décolletage was often a feature of the dress of the late Middle Ages; this continued through the Victorian period. Gowns that exposed a woman's neck and the top of her chest were very common and uncontroversial in Europe from at least the 11th century until the mid-19th century. Ball gowns and evening gowns especially had low, square décolletage that was designed to display and emphasize cleavage.

In many European societies between the Renaissance and the 19th century, wearing low-cut dresses that exposed breasts was more acceptable than it is in the early 21st century; bared female legs, ankles and shoulders were considered to be more risqué than exposed breasts. In aristocratic and upper-class circles, the display of breasts was at times regarded as a status symbol; a sign of beauty, wealth and social position. The bared breast invoked associations with nude sculptures of classical Greece that influenced the art, sculpture and architecture of the period.

In mid-16th-century Turkey, during the reign of Suleiman the Magnificent, respectability regulations allowed "respectable" women to wear fashionable dresses with exposed cleavage; this priveledge was denied to "prostitutes" so they cannot draw attention to their livelihoods. The entari, a popular women's garment of the Ottoman Empire, resembled the corseted bodice of Europe without the corset; its narrow top and narrow, long, plunging décolletage exposed a generous cleavage. Around this time, cleavage-revealing gambaz gowns became accepted among married women in the Levant, where bosoms were regarded as a sign of maternity.

In 16th-century India, during the Mughal Empire, Hindu women started emulating the overdressed conquerors by covering their shoulders and breasts, though in contemporaneous paintings, women of Mughal palaces were often portrayed wearing Rajput-style cholis and breast jewelry. Mughal paintings often portrayed women with extraordinarily daring décolletage. Contemporaneous Rajput paintings often depict women wearing semi-transparent cholis that cover only the upper part of their breasts. In the 16th century, when Spanish conquistadors colonized the Inca Empire, traditional cleavage-revealing and colorful Inca dresses were replaced by high necks and covered bosoms.

Anne of Austria, Queen of France, was an early 17th century fashion icon wearing dresses that showcased her cleavage

In European societies during the 16th century, women's fashions with exposed breasts were common across the class spectrum. Anne of Brittany has been painted wearing a dress with a square neckline. Low, square décolleté styles were popular in 17th-century England; Queen Mary II and Henrietta Maria, wife of Charles I of England, were depicted with widely bared breasts. Architect Inigo Jones designed a masque costume for Henrietta Maria that widely revealed both of her breasts. Cleavage-enhancing corsets, which used whalebone and other stiff materials to create a desired silhouette—a fashion that was also adopted by men for their coats—were introduced in the mid-16th century.

Throughout the 16th century, shoulder straps stayed on the shoulders but as the 17th century progressed, they moved down the shoulders and across the top of the arms, and by mid-17th century, the oval neckline of the period became commonplace. By the end of the century, necklines at the front of women's garments started to drop even lower. During the extreme décolletage of the Elizabethan era, necklines were often decorated with frills and strings of pearls, and were sometimes covered with tuckers and partlets (called a tasselo in Italy and la modiste in France). Late Elizabethan corsets, with their rigid, suppressive fronts, manipulated a woman's figure into a flat, cylindrical silhouette with a deep cleavage. Contemporaneous French fashion started to gain popularity in Italy; these fashions included the Sapnish-style high neckline and face-framing ruff, replacing House of Medici-style décolletage.

Around 1610, flat collars started replacing neck trims, allowing provocative cleavage that was sometimes covered with a handkerchief. During the Georgian era, pendants became popular as décolletage decoration. Anne of Austria, along with female members of her court, was known for wearing very tight bodices and corsets that forced breasts together to make deeper cleavage, very low necklines that exposed breasts almost in entirety above the areolae, and pendants lying on the cleavage to highlight it. After the French Revolution décolletage become larger at the front and reduced at the back. During the fashions of 1795–1820, many women wore dresses that bared necks, bosoms and shoulders. Increasingly, the amount of décolletage became a major difference between day-wear and formal gowns.

Cleavage was not without controversy. In 1713, British newspaper The Guardian complained about women mostly eschewing the tucker, and letting their necks and the tops of their breasts remain uncovered. English poet and essayist Joseph Addison complained about décolletage so extreme "the neck of a fine woman at present take in almost half the body". Publications advised women against "unmasking their beauties". 18th-century news correspondents wrote that "otherwise polite, genteel women looked like common prostitutes".

During the French Enlightenment, there was a debate about whether female breasts were merely a sensual enticement or a natural gift to be offered from mother to child. Not all women in France wore the open-neck style without modifications; a self-portrait by Adélaïde Labille-Guiard (France, 1785) shows the painter in a fashionable décolleté dress while her pupils have their bosoms accessorized with gauzy handkerchiefs. Nearly a century later, also in France, a man from the provinces who attended a court ball at the Tuileries in Paris in 1855 was disgusted by the décolleté dresses and is said to have said; "I haven't seen anything like that since I was weaned!". In 1890, the first breast augmentation was performed using an injection of liquid paraffin.

By the end of 18th century in Continental Europe, cleavage-enhancing corsets grew more dramatic, pushing the breasts upward. The tight lacing of corsets worn in the 19th and early 20th centuries emphasized both cleavage and the size of the bust and hips. Evening gowns and ball gowns were especially designed to display and emphasize the décolletage. Elaborate necklaces decorated the décolletage at parties and balls by 1849. There was also a trend of wearing camisole-like clothes and whale-bone corsets that gave the wearer a bust without a separation or any cleavage. Despite the contemporaneous popularity of décolletage dresses, complete exposure of breasts in portraits was limited to two groups of women; the scandalous (mistresses and prostitutes), and the pure (breastfeeding mothers and queens). In North America, the Gilded Age saw women adorning their cleavage with flowers attached to clothes and carefully placed jewelry.

During the Victorian period of the mid-to-late 19th century, social attitudes required women to cover their bosoms in public. High collars were the norm for ordinary wear. Towards the end of this period, the full collar was in fashion, though some décolleté dresses were worn on formal occasions. For that purpose, the Bertha neckline, which lay below the shoulders and was often trimmed with three to six inches (7.6 to 15.2 cm) of lace or other decorative material, became popular with upper and middle-class women but it was socially unacceptable for working class women to expose that much skin. Multiple pearl necklaces were worn to cover the décolletage. Along with the Bertha neckline, straps were removed from corsets and shawls were made essential.

Italian soprano Lina Cavalieri, known for her décolletage as much as her talent, at the turn of the 20th century. She was potrayed in her biopic The World's Most Beautiful Woman by Gina Lollobrigida, the Italian actress engaged in a "cleavage war" with her archrival Sophia Loren.

By 1904, necklines of evening attire were lowered, exposing the shoulders, sometimes without straps but the neckline still ended above the cleavage. Clergymen all over the world were shocked when dresses with modest round or V-shaped necklines became fashionable around 1913. In the German Empire, Roman Catholic bishops issued a pastoral letter attacking the new fashions. In the Edwardian era, extreme uplift with no hint of cleavage was as common as a bow-fronted look that was also popular. In 1908, a single rubber pad or a "bust form" was worn inside the front of the bodice to make cleavage virtually undetectable.

The Flapper generation of 1920s flattened their chests to adopt the fashionable "boy-girl" look by either bandaging their breasts or by using bust latteners. Corsets started to go out of fashion by 1917, when metal was needed to make tanks and munitions for World War I and due to the vogue for boyish figures. In New Zeland, the early appearance of décolleté clothes in 1914 was soon superseded by the "flat" fashion. Breast suppression prevailed in the Western world so much the U.S. physician Lillian Farrar attributed "virginal atrophic prolapsed breasts" to the fashion imperatives of the time. In 1920, paraffin was replaced for breast augmentation with fatty tissue taken from the abdomen and buttocks.

Marilyn Monroe, in Some Like It Hot (1959). She once said, "The trouble with censors is that they worry if a girl has cleavage. They ought to worry if she hasn't any." She was voted a cleavage queen 50 years after her death.

Frustrated with the whalebone corset, New York socialite Mary Phelps Jacob (better known as Caresse Crosby) created the first brassière from two handkerchiefs and some ribbon to show off her cleavage. In 1914, Jacob patented the garment as "the backless brassiere"; after making a few hundred garments, she sold the patent to The Warner Brothers Corset Company for US$1,500. In the next 30 years, Warner Brothers made more than US$15 million from Jacob's design. During the next century, the brassière industry went through many ups and downs, often influenced by the demand for cleavage.

With a return to more womanly figures in the 1930s, corsetry maintained a strong demand, even at the height of the Great Depression. From the 1920s to the 1940s, corset manufacturers constantly tried training young women to use corsets but fashions became more restrained in terms of décolletage while exposure of the leg became more accepted in Western societies during World War I and remained so for nearly half a century. In the Republic of China in the early 20th century, qipao, a dress that shows the legs but no cleavage, became so popular many Chinese women consider it as their national dress.

In the 1940s, a substantial amount of fabric in the center of brassières created a separation of breasts rather than a pushed-together cleavage. In 1947, Frederick Mellinger of Frederick's of Hollywood created the first padded brassière followed a year later by an early push-up version dubbed "The Rising Star". In that decade, Christian Dior introduced a "new look" that included elastic corsets, pads and shaping girdles to widen hips, cinch waists and lift breasts.

Under the Motion Picture Production Code, which was in effect in the U.S. between 1934 and 1968, the depiction of excessive cleavage was not permitted. Many female actors defied those standards; other celebrities, performers and models followed suit and the public was not far behind. Low-cut styles of various depths were common. In the post-war period, cleavage became a defining emblem; according to writer Peter Lewis; "The bust, bosom or cleavage was in the Fifties the apotheosis of erogenous zones. The breasts were the apples of all eyesyy." Around this time, the American word "cleavage" started to be used to define the space between the breasts.

In their haydays, Wonderbra sponsored a National Cleavage Day in South Africa every year, and the webcast of the Victoria's Secret show became one of Internet's biggest events.

According to an urban American woman, during the 1950s, "At night our shoulders were naked, our breasts half-bare". Dramatic necklaces that emphasized the cleavage became popular at balls and parties in France. In the U.S., television shows tried to mask exposed cleavage with tulle and even sketches, illustrations and short stories in Reader's Digest and Saturday Evening Post depicted women with tiny waists, big buttocks and ample cleavage. In this decade, Hollywood and the fashion industry successfully promoted large, cloven bustlines and falsies, the brassière industry started experimenting with the half-cup bra (also known as demi-cup or shelf bra) to facilitate décolletage. Polyvinyl sacs were often the preferred implant to augment breasts into a fuller, more projected appearance.

Despite these developments, open presentation of cleavage was mostly limited to well-endowed female actors like Lana Turner, Marilyn Monroe (who was accused of revealing America's "mammary madness" by journalist Marjorie Rosen), Rita Hayworth, Jane Russell, Brigitte Bardot, Jayne Mansfield and Sophia Loren, who were as celebrated for their cleavage as for their beauty. While these movie stars significantly influenced the appearance of women's busts in this decade, the stylish 1950s sweaters were a safer substitute for many women. Lingerie manufacturer Berlei launched the "Hollywood Maxwell" brassière, claiming it to be a "favourite of film stars".

Modern augmentation mammaplasty began when Thomas Cronin and Frank Gerow developed the first silicone gel-filled breast prosthesis with Dow Corning Corporation, and the first implanting operation took place the following year. In the late 1960s, attention began to shift from the large bust to the trim lower torso, reasserting the need to diet, especially as new clothing fashions—brief, sheer, and close fitting—prohibited heavy reliance on foundation lingerie. Legs were comparatively less emphasized as elements of beauty.

In the 1960s, driven by second-wave feminism, liberal politics and the free love movement, a bra burning movement arose to protest against—among various patriarchal imperatives—constructed cleavage and disciplined breasts. Yves Saint Laurent and U.S. designer Rudi Gernreich experimented with a bra-less look on the runway. The increasingly casual styles of the 1960s led to a bra-less look when women who were unwilling to give up bras turned to soft bras that did not lift and "were as light and discreet as possible" but still provided support.

From the 1960s, changes in fashion leaned towards increased displays of cleavage in films and television; Jane Russell and Elizabeth Taylor were the biggest stars who led the fashion. In everyday life, low-cut dress styles became common, even for casual wear. Lingerie and shapewear manufacturers like Warner Brothers, Gossard, Formfit and Bali took the opportunity to market plunge bras with a lower gore that was suitable for low-cut styles.

In the early 1970s, it became common to leave top buttons on shirts and blouses open to display pectoral muscles and cleavage. Daring women and men of all ages wore tailored, buttoned-down shirts that were open from the breast-point to the navel in a "groovy" style, with pendants, beads or medallions dangling on the chest, displaying a firm body achieved through exercise. Throughout the 1970s, more men unbuttoned their shirts as both men and women took an anti-fashion approach to clothing and the rise of the leisure wear, and adopted comfortable, unisex styles. As a new masculine style evolved, gay men adopted a traditionally masculine or working-class style with "half-unbuttoned shirt above the sweaty chest" and tight jeans, rejecting the idea male homosexuals want to be female.

During the 1980s, deep, plunging cleavage became more common and less risqué as the popularity of work-outs and masculine shoulder-padded blazers increased. In 1985, designer Vivienne Westwood re-introduced the corset as a trendy way to enhance cleavage. It was followed in 1989 by Jean Paul Gaultier, who dressed Madonna in a pink corset. Soon, Westwood introduced a elastic-sided variant that worked as a balcony to push up the cleavage.

The push-up bra and exaggerated cleavage became popular in the 1990s. In 1992, the bra and girdle industry in America posted sales of over US$ 1 billion. The Wonderbra brand, which had existed elsewhere, entered the U.S. market in 1994 with a newly designed, cleavage-enhancing bra. Driven by a controversial advertising campaign that featured model Eva Herzigova's cleavage, one Wonderbra was sold every 15 seconds shortly after the brand's launch, leading to first-year sales of US$ 120 million. The hypersexualized styles of Victoria's Secret became a "zeitgeist" in the 1990s. By 2013, Victoria's Secret had captured one-third of the women's underwear market in the U.S. In the early 1990s, Sara Lee Corporation—hen owner of the Wonderbra and Playtex brands—along with UK lingerie manufacturer Gossard, introduced a bra for Asian women who, according to Sara Lee, are "less buxom [and have] narrower shoulders". Traditional brands like Maidenform produced similar styles.

In the late-20th-century India, cleavage became a staple point of attraction in Bollywood movies. By 2010s, Indian men and women wearing décolleté clothes were seen as fashion statements and not, asin the past, as a sign of desperation. At the same time, onscreen cleavage waned as a point of attraction as cleavage-revealing clothes became more commonplace. Both male and female respondents to a 2006 study conducted in Mumbai, young people believe that women wearing cleavage revealing filmi (movie-like) clothes may be more prone to become victims of sexual violence.

Underwire bras, the most popular cleavage-boosting lingerie, accounted for 60% of the UK bra market in 2000. and 70% in 2005. About 70% of women who wear bras wear a steel underwire bra according to underwear manufacturer S&S Industries of New York in 2009. In 2001, 70% (350 million) of the bras sold in the U.S. were underwire bras. As of 2005, underwire bras were the fastest-growing segment of the market.

Corsets also experienced a resurgence in the 2010s; this trend was driven by photographs on social media. According to fashion historian Valerie Steele, "The corset did not so much disappear as become internalised through diet, exercise and plastic surgery". By the turn of the 21st century, some of the attention given to cleavage and breasts started to shift to buttocks, especially in the media, and corsetry returned to mainstream fashion. According to dietician Rebecca Scritchfield, the resurgent popularity of corsets is driven by "the picture on Instagram of somebody with a tiny waist and giant boobs". At the same time alternatives to décolletage, which were often still called cleavages, emerged from Western cleavage culture.

By the early 2010s, "sideboob" (also known as "side cleavage"), i.e. the exposure of the side of the breast had become popular. One writer called it the "new cleavage". In 2008, Armand Limnander wrote in The New York Times the "underboob" (also known as "bottom cleavage" and "reverse cleavage") was "a newly fetishized anatomical zone where the lower part of the breast meets the torso, popularized by 80s rock chicks in cutoff tank tops". It was further popularized by dancer-singer Teyana Taylor in the music video for Kanye West's 2016 song "Fade". Supermodels, including Bella Hadid, Gigi Hadid, and Kendall Jenner, contributed to the trend, which has appeared at beaches, on the red carpet, and in social media posts.

In the 2010s and early 2020s, particularly during the 2020 COVID-19 pandemic lockdowns, cleavage-enhancing bras began to decline in popularity. Bralettes and soft bras gained market share at the expense of underwire and padded bras, sometimes also serving as outerwear. Some bralettes have plunging designs, light padding or bottom support. In November 2016, the UK version of fashion magazine Vogue said "Cleavage is over"; this statement was widely criticized. Soft bras and sideboobs became popular over prominent cleavages. Soft bras consisted 30% of online retailer Net-a-Porter's bra sales by 2016. In 2017, the sales of cleavage-boosting bras fell by 45% while at Marks & Spencer, sales of wire-free bras grew by 40%.

Jess Cartner-Morley, fashion editor of The Guardian, reported in 2018 many women were dressing without bras, producing a less-dramatic cleavage, which she called "quiet cleavage". According to Sarah Shotton, creative director of Agent Provocateur, "Now it’s about the athletic body, health and wellbeing" rather than the male gaze. According to lingerie designer Araks Yeramyan, "It was #MeToo that catapulted the bralette movement into what it is today". During the COVID-19 lockdowns, CNBC reported a drop of 12% in bra sales across 100 retailers while YouTubers made tutorials on re-purposing bras as face masks; this trend was sometimes called a "lockdown liberation".

Enhancement

Throughout history, women have used many methods, including accentuation and display of breasts within the context of cultural norms of fashion and modesty, to enhance their physical attractiveness and femininity. Fetishization of breasts results in significant anxiety in females about having the correct breasts and resulting cleavage. All kinds of exercises, brassières and other methods of bust improvement have been recommended and advertised to cater for this need.

Corsetry and bras

Corsetry and bras are often used to enhance cleavage. It has been said the quickest way for a women to change her breasts is to buy a bra. Before the brassière became popular, the bust was encased in corsets and structured garments called "bust improvers", which were made of boning and lace. When corsets became unfashionable, brassières and padding helped to project, display and emphasize the breasts. These were initially manufactured by small companies and supplied to retailers. Women had the choice of long-line bras, built-up backs, wedge-shaped inserts between the cups, wider straps, Lastex, firm bands under the cup, and light boning. In 2020, several lingerie and shapewear manufacturers, among them Wonderbra, Frederick's of Hollywood, Agent Provocateur and Victoria's Secret, produce bras that enhance cleavage and offer more than 30 types of bra, including underwire, padded, plunge and push-up bras.

Development of underwire bras started in the 1930s but they did not gain widespread popularity until the 1950s, when the end of World War II freed metal for domestic use. In an underwire bra, a thin strip of metal, plastic or resin—usually with a nylon coating at both ends—is sewn into the bra fabric and under each cup from the center gore to the armpit. The insert helps to lift, separate, shape and support the breasts. Underwire bras can rub and pinch the breast, causing skin irritation and breast pain, and the wire of a worn bra can protrude from the fabric and scrape or cut the skin.

Padded bras have extra material, which may be foam, silicone, gel, air or fluid, in the cups to help the breasts look fuller. Different designs provide coverage and support, hide nipples, add shape to breasts that are far apart, and add comfort. Graduated padding has more padding at the bottom of the cups and gradually tapers towards the top. Some padded bras are made to suit deep-neck dresses.

Plunge bra covers the nipples and the lower part of the breasts while leaving the top part bare, making it suitable for low-cut tops and deep V-necks. Plunge bras also have a lower, shorter and narrower center gore that maintains support while increasing cleavage by allowing the gore to drop several inches below the middle of the breasts. Plunge bras may be padded or push the breasts together to create cleavage.

Push-up bras, which emerged in the mid-20th century, are designed to press the breasts upwards and closer together to give a fuller appearance with help of padded cups, differing from other padded bras in location of the pads. It leaves the upper and inner area of breats uncovered adding more cleavage. Most of the push-up bras have underwires for added lift and support, while the padding is commonly made of foam. Wonderbra used to have 54 design elements in their push-up bras, including a three-part cup, underwires, a precision-angled back, rigid straps, and removable "cookies".

Cleavage wrinkles can be caused by sleeping on the side, which makes the top breast to bend past the body's midline, or long hours wearing a sports bras or a push-up bra that presses breasts together. These deep, vertical creases stay longer as the collagen in skin start to breakdown with age and exposure to sun. Women with large breasts, either natural or surgically enhanced, suffer more from cleavage wrinkles. Cleavage wrinkles are treated by botox and, according to Wilson, Intense pulsed light (IPM), Collagen Induction Therapy (CIT) and High-intensity focused ultrasound. In some forms of exercise, breasts unsupported by a sports bra are exposed to greater risk of droopiness.

Tape and inserts

Accessories, including lingerie tapes or duct tapes, removable gel pads, fabrics, silicone or microfiber inserts, and clothing—including socks—are used to enhance cleavage. Many women, such as beauty pageant participants and transgender people, create cleavage by placing tape underneath and across their breasts, bending forward, tightly pulling them together and up. Types of tape used include lingerie tape, surgical tape and athletic tape. Some use a strip of moleskin under the breasts; this is held in place with tape. Use of the wrong techniques or tape with too strong an adhesive can cause injuries such as rashes, blisters and torn skin.

Falsies, small silicone-gel pads that are similar to the removable pads sold with some push-up bras, are sometimes referred to colloquially as "chicken fillets". Falsies evolved from the bosom pads of the 17th century that were often made of stiff rubber. By the mid 1800s,"bust improvers" were made using soft fabric pads of cotton and wool or inflatable rubber. In 1896, celluloid falsies were advertised and in 20th century, soft foam rubber pads became available. Young women, some as young as 15, were expected to wear falsies to fill out their bodices.

Surgery

Cleavage, from a surgical perspective, is a combination of the intermammary distance and the degree of "fill" in the medial portion of the breast. Some flat-chested women feel self-conscious about their small breasts and want to improve their sexual attractiveness by seeking breast augmentation. According to plastic surgeon Gerard H. Pitman; "you can't have cleavage with an A cup. You have to be at least a B or a C." It is easier to push big breasts together to accent the hollow between them. Implants filled with sterile saline solution and implants filled with viscous silicone gel are used for breast reconstruction, and for the augmentation and enhancement of aesthetics—size, shape, and texture—of breasts. Plastic surgeons changed from using bodily tissues to these newer technologies in the 1950s.

Sometimes, fat is injected into the subcutaneous plane to narrow the gap of the cleavage and is grafted onto wide-chested individuals. During breast reconstruction, surgeons are normally careful to preserve the natural cleavage of the breasts. Attempts to create or increase cleavage by loosening the medial borders of the breasts could result in symmastia (also called a "uniboob"), a confluence of the breast tissue of both breasts across the midline in front of the sternum, creating a lack of defined cleavage. About 3 cm of cleavage distance is recommended while augmenting breasts, to avoid medial perforation, compromised soft tissues, visible implants, rippling and symmastia. A high surgical release of pectoralis major muscles can enhance cleavage at the risk of the implant showing through soft tissues.

A 2016 paper reported breast augmentation was one the most common aesthetic surgery procedures performed by plastic surgeons. Annually, an estimated 8,000–20,000 surgeries are done in the UK and over 300,000 in the U.S. According to the paper, in the U.S., 4% of women had breast implants at the time. It reported annual sales of 300,000 implants in South America and estimated the global number of women with breast implants to be between five and ten million.

Women seeking breast augmentation often request a specific form of cleavage enhancement and often produce photographs of desired cleavage shapes and appearances. Many of those who seek breast augmentation want "full cleavage" which, according to plastic surgeon Jeffrey Weinzweig, "in reality results only from external forces, such as a brassier. Attempts to create such full cleavage require unacceptable compromise to other aesthetic factors of the breast."

The width of cleavage is determined at the point at which the breast tissue attaches to the periosteal bone membrane that covers the sternum and by the medial attachments of the pectoralis major (chest muscle). By modern cultural values, cleavage is considered more attractive when breasts are close together. A narrow cleft between the breasts is identified as unusual anatomy. Plastic surgeon John B. Tebbetts finds creating a narrow intermammary distance is not a priority over other aspects. He says if a patient wishes a gluteal appearance for her cleavage, she should use "an appropriate push up brassiere", avoiding "the temptation to create it surgically". Because large breasts are not always closer together than smaller ones, and because implants change only the volume of the breasts, not their position, implants cannot produce a tight cleavage if the gap between the breasts is wide. Wide-set breasts will have a wide cleavage even after surgery because implants cannot correct the condition.

Exercise and supplements

Exercise on a machine fly, a recommended way to develop cleavage

Regular exercise of the muscles and fibers of the pectoral complex, which lies just under the fatty tissues of the breast, helps prevent droopiness, creates the illusion of larger and firmer breasts, and enhances cleavage. Exercise does not enlarge the breasts but developing the pectoral muscles on the chest can give them a fuller appearance. Training the chest does not change the structure of the breasts because breast tissue is fat, which cannot be shaped; chest training can, however, prevent breasts from drooping and sagging by firming the muscles that surround the sternum. Even in moderately athletic women, the pectoralis major muscles on either side of the cleavage become more prominent with exercise.

The most effective exercises for developing breasts and improving cleavage are incline chest press, chest fly and chest dip. Weight training, nautilus machines, push-ups and chest presses are helpful, as are exercise balls, dumbbells, rowing and basketball. Flat chest dumbbell pullovers and dumbbell flyers on incline bench is recommended for beginners, while the advanced exercisers may include bench press movements, flyers, pullovers, Pec Decs and push-ups at least twice a week.

Bhujangasana (cobra pose) is one of the most recommended yoga poses for cleavage improvement

Pilates, Tai Chi andyoga boost cleavage by improving posture and strengthening the chest muscles. Hunching, tightening and closing off of the chest in yoga asanas are particularly helpful, along with breathing exercises like deep breathing (sama vritti or kapalabhati) and retention (kumbhaka). The most recommended asanas to develop cleavage are backbends like cobra, bow, camel, bridge and locust ; twisted poses like cow face and lord of fishes; front bends like plough and resting child; standing poses like tree and warrior; and leg stretches like raised leg and inverted leg stretch.

Supplements are frequently portrayed as natural means to increase breast size with the suggestion they are free from risk. Commonly used ingredients include black cohosh, (shown to have no estrogenic effect) dong quai, hops, kava (may cause liver damage) and zearalenone (increases probability of estrogen-dependent breast cancer and may reduce fertility) among others. Despite folklore about using herbs for breast enlargement, there is no scientific evidence to support the effectiveness of any breast enlargement supplement. In the United States, both the Federal Trade Commission and the Food and Drug Administration have taken action against the manufacturers of these products for fraudulent practices.

Grooming and make up

Sunburnt upper décolletage (neck and shoulder)

According to Samantha Wilson, founder of skincare product manufacturer Skin Republic, dermatologist Paul Jarrod Frank, and Philippa Curnow of Elizabeth Arden, compared with the epidermis on the face, the epidermis on the cleavage and neck has fewer hair follicles and oil glands, little subcutaneous fat cushioning the area, a limited number melanocytes, and is much thinner and more fragile. Skin in these areas can suffer from damage resulting in cleavage wrinkles, uneven skin tone, age spots, scars from heat rash, and female chest hairs, and may show loss of elasticity sooner. According to Curnow, the skin of the cleavage area often ages more quickly because it experiences more exposure to ultraviolet radiation (UV) and environmental factors like pollution than skin that remains covered in many cultures, while moisturizers and sunscreens are used more on the face and neck. According to Marnina Diprose, founder of skin care clinic Aroze Dermal Therapies, ultraviolet radiation can break down collagen and cause pigment deposition, leading to mottled pigmentation on the cleavage. The skin of the cleavage area may also show loss of elasticity more quickly.

Products routinely used on the face, including vitamin A, vitamin B3, and vitamin C, masks, cleansers, moisturizers, and exfoliators, are also applied to the cleavage. Regular use of sunscreen is recommended by reconstructive surgeon Dr Anh Nguyen. Products specifically designed for the cleavage and neck and also available. Body oils like shea butter, coconut oil and almond oil,) and bronzers can help give a "glowing" cleavage. Splashing cold water on the cleavage also helps.

Dermatoheliosis (photo aging) is a problem when cleavage skin is exposed for prolonged periods to UV radiation in sunlight; it is characterized by hyperpigmentation, leathery texture, roughness, wrinkles, lentigines (age spots), actinic elastosis and telangiectasias (spider veins). Use of high-factor sunscreen on the cleavage area is also recommended. Some perfumes and colognes can cause a phototoxic rashes on the neck, wrists and cleavage that leaves patterned hyperpigmentation when healed.

Makeup with shading effects can be used to make cleavage appear deeper and the breasts look fuller. The middle of the cleavage is made to look deeper by using a shade of makeup color that is darker than the base color of the skin, while the most prominent areas of the breasts are made to look larger or more protruding by the use of a paler color. An illuminator on the collar bones and bronzing below them is also advised. Beauty journalist Zoe Weiner recommends outlining the breasts with a contouring stick that is slightly darker than the skin tone then hightlighting inside the contour lines with a highlighter slightly lighter than skin tone, followed by blending with a contouring brush in circular motions. According to Victoria's Secret model Taylor Hill, most professional models use makeup to better define their cleavage. Makeup artist Stephen Dimmick recommends using a luminizer on the clavicle area.

Embellishments

Cleavage piercing

Cleavage tattoo

Bright colors, ornaments and accessories, including ruffles and glitters that add detail to the cleavage area, help to make breasts look bigger and draw attention to them. Using the cleavage as a canvass, a recommended way of adornment is to layer necklaces and chokers with a pendant as a centerpiece of the cleavage. Georgian era-style rivière necklaces are also popular items with which to dress the decolletage.

According to celebrity tattoo artist and tattoo historian Lyle Tuttle, sternum tattoos became popular with women's liberation. Singer Rihanna was a major driver in popularizing cleavage tattoos. According to tattooist Mira Mariah, "Since most sternums are a flat plane, there are really good opportunities for detail". Underboob tattoos are generally done under the breasts but could wrap around the sternum, cleavage, side boob and ribs.

Cleavage piercings, also known as chest piercings and sternum piercings—one of the most-admired body piercings—is done on the cleavage area vertically or horizontally. A sternum piercing can be located anywhere along the sternum and can be either a surface piercing or a dermal piercing. The jewelry, generally flexible rods made of hypoallergenic metal like surgical titanium, surgical stainless steel, niobium or gold (14 karat and above), is placed vertically or horizontally between the breasts.

Male and transgender cleavage

Male cleavage (also known as "heavage"), a result of low necklines or unbuttoned shirts, has been a movie trend since 1920s. Douglas Fairbanks revealed his chest in films including The Thief of Bagdad (1924) and The Iron Mask (1929), and Errol Flynn showed his male cleavage in movies like The Adventures of Robin Hood (1938). This aesthetic continued into the 1950s and 1960s with movie stars like Marlon Brando, who also displayed his chest in The Adventures of Robin Hood, and Sean Connery in his many James Bond movies. The fashion tapered out since 1970s, which according to fashion historian Robert Bryan, was "the golden age of male chest hair", epitomized by John Travolta in Saturday Night Fever (1977).

This look was also popular with celebrities like Mick Jagger and Burt Reynolds in the 1970s, and Harry Styles, Jude Law, Simon Cowell and Kanye West in the 2010s. In India, male cleavage became popular with Bollywood movie stars Salman Khan (who was named "the king of cleavage" by The Economic Times), Shekhar Suman in the 1990s, and Shahid Kapoor and Akshay Kumar in the 2000s. Many male K-pop stars are also known for their cleavage.

Man cleavage came back into style in the 2010s, especially among hipsters and Hispanic and Latino Americans. Stylist Christiaan Choy attributes its resurgence to fit physiques and the urge for personal styles. Fashion entrepreneur Harvey Paulvin said a men's V-neck should be between "two to four inches from the collar". Some men groom their chest hair to improve the male cleavage look (sometimes known as "manscaping"). Many still considered the look inappropriate for most situations.

Male bra for transgender men

Gynecomastia, an endocrine disorder that causes breast development in males (also known as man boobs or moobs) and prominent male cleavage, and can result in psychological distress. Some men wear a male bra (also known as "compression bra" or "compression vest"), which typically flattens the cleavage rather than giving it a lift. Exercises like cardio and strength training are also recommended in reducing a man cleavage. In more severe cases, medical treatment may include surgical intervention. According to British Association of Aesthetic Plastic Surgeons (BAAPS), 323 men had breast reduction surgery in 2008 in the UK, which is 44% more than in 2007.

Male cross-dressers and transwomen often want female-like cleavage to make their bodies look more feminine. Convincing cleavage may distract attention from less-feminine aspects of the appearance and improve the ability to pass. For cross-dressers or transwomen who have not undergone hormone therapy or breast augmentation, semi-rigid pieces of material such as plastic can be applied to the skin using surgical tape, surgical adhesive or specialist adhesives. General-purpose craft glue can be also used for this purpose.

A garment called a "Diva" has bra-style fasteners at the front instead of the back and has cups that curve inwards, are fairly rigid and covered on the inside with a material that uses pressure to grip the skin to hold it in place. Another device is called the "Busty Cleavage Creator", which uses a pair of crossed Velcro straps on the front to pull the skin towards the center, leaving an uneven surface for the breast forms to sit against. Adhesive gel bras consist of two shaped silicon gel-filled bra cups that stick to the skin of the breast using re-usable adhesive then clip together to pull the breasts together. It is difficult to produce sufficiently feminine cleavage for transwomen, even with breast augmentation surgery, because people assigned male at birth have nipple-areolar complexes set farther apart on their chests than do those assigned female at birth. Fat grafting may be used to reduce the width of cleavage in transwomen.
