White tie (or full dress, evening dress, full evening dress; slang top hat and tails or white tie and tails, tailsuit, tails) is the most formal evening dress code in Western fashion. It is worn to ceremonial occasions such as state dinners in some countries, as well as to very formal balls and evening weddings.
The chief dress code components for White Tie for men are:
- Starched wing collar shirt
- White bow tie
- White waistcoat
- The black dress coat commonly known as an evening tailcoat
Women wear a suitable dress for the occasion, such as a ball gown.
As evening dress, white tie is traditionally considered correct only after 6:00 p.m. although some etiquette authorities allow for it any time after dark even if that means prior to 6:00 p.m. (though there are some exceptions). The equivalent formal attire for daytime events is called morning dress. The semi-formal evening counterpart of white tie is black tie.
The invention of white tie is widely accredited to Beau Brummell (1778–1840), who simplified and codified evening dress at the time. Many essential elements introduced by him are still reflected in today's white tie to a certain degree such as the monochromatic colour scheme and the use of coat, waistcoat and trousers.
Although the use of white tie had been slowly in decline since the First World War, there has been a recent resurgence in interest in the early part of the 21st century, partially due to successful period dramas such as Downton Abbey, the vintage movement and its adoption by prolific people/groups such as The Hives who have worn it as their band outfit since 2011.
Formal evening dress is strictly regulated, and properly consists of:
- Black silk socks or stockings
- Trousers of matching fabric with one wide or two narrow strips of braid down the side seams
- Black court pumps (with black silk bows) or Oxfords
- White plain stiff-fronted cotton shirt, with white pique dickie
- White stiff wing collar, sometimes detachable
- White pique cotton bow tie
- White low-cut pique waistcoat
- Black or midnight blue dress coat (commonly known as an evening tailcoat) with silk (grosgrain or satin) facings, horizontally cut-away at the front
The coat (or 'body coat' as tailors call it) is cut to hug the body closely and is detailed in the seams at the back of the coat and the waist seam. The lapels can be pointed or have a shawl collar; faced with either silk satin or grosgrain although other types of silk can be used including moiré and barathea weave. The colour of the facings should be black or, in the case of a midnight-blue coat, be either black or midnight-blue. The coat is cut so it is worn open and cannot be buttoned; the two sides should never meet. There are usually six decorative buttons, three on each side, which are either of polish black horn/bone or covered in silk which could be the same as that of the facings or figured. The cuffs usually have four buttons. The fronts are cutaway at a sharp angle and the tails have a single vent. There are two styles of cut for the coat; the older cut with 'laid-on' lapels where the lapels are attached as a separate piece onto the body, and the modern 'grown-on' lapel with the lapel cut as part of the body and shaped using darts.
The trousers are of the same cloth as the coat and either have a very wide single line of braid or two narrow lines of braid sewn very close together running down both side seams. They are usually cut with a high-rise so the fronts of the coat cover the waistband completely in order for the waistcoat to cover the waistband easily. They are worn with braces (suspenders in American English) to avoid disrupting the lay of the waistcoat in the case of a belt being worn and to keep the trouser creases aligned.
The waistcoat and bow tie are usually made of cotton marcella (known in American English as "piqué"), although plain white, off-white or ivory silk bow ties and waistcoats are sometimes worn. Black wool waistcoats were once the norm for full dress as the alternative to the white but it is now rarely worn. The waistcoat is cut low, that is, the opening is low to allow much of the shirt front with their studs to be displayed. It is either single or double breasted, with or without revers/lapels, and can be fully backed or backless. Button numbers vary depending on style and are almost always detachable to allow the waistcoat to be cleaned and starched. The bow tie also exists in various widths and styles.
Many menswear authorities today assert that the bottom of the waistcoat should not be visible below the front cutaway of the tailcoat. This has been the prevalent view in the United States since the 1920s, where actors such as Fred Astaire popularized the look of the unbroken black line from neck to feet which lengthened their silhouettes on-camera. The practice was also reinforced repeatedly by authorities dating back to at least World War I and is adhered to in numerous fashion magazines dating back to at least the 1840s. However, since full evening dress is the most conservative form of men's dress, and has otherwise changed very little since the 1870s when the bottom of the waistcoat was visible below the cutaway of the tailcoat, some traditionalists (especially in Europe and among the aristocracy) tend to wear the waistcoat with its hem extending below the cutaway of the tailcoat by 1–2 cm. As for British royal authority on the matter, the waistcoat does not extend below the fronts. Worn either style, the waistcoat must cover the trouser waistline (which should never be seen).
The shirt should have a detachable stand-up or wing collar, with a plain but stiffly starched bib front and cuffs, though shirts with attached collars are becoming more prevalent. Shirt fronts can be plain linen, plain cotton or cotton marcella and are closed with studs.
Shirt studs, cufflinks and waistcoat buttons could be silver, gold or other precious metals, faced with mother-of-pearl or other semi-precious stones and ideally all matching in a set. A white pocket handkerchief and boutonnière may be worn (although in France both may not be worn simultaneously and the boutonnière is traditionally a gardenia). The timepiece is either a pocket watch suspended from a ribbon fob (worn inside the fob pocket of the trousers) or an Albert chain (worn in a pocket of the waistcoat). Wristwatches are never to be worn.
At occasions of state, and in the presence of royalty, state decorations are worn by those who have been awarded them: miniature medals plus up to four breast stars, a badge suspended from a narrow neck riband and a broad riband (sash).
The hat should be a black silk top hat which may be collapsible — a tradition which arose from the fact that opera houses traditionally lacked a cloak room to hand in a top hat. The overcoat should be a dark dress coat such as a Chesterfield overcoat, Inverness cloak, or opera cloak. White gloves were traditionally considered essential and are often worn for dancing, but must be removed when dining. A silk scarf and cane are optional extras.
At some state and heraldic occasions in Britain, knee-breeches and silk stockings are worn instead of trousers, also known as 'alternative court dress'. This is particularly necessary where the garter of the Order of the Garter is intended to be worn. If a Knight of the Garter wears breeches, he wears his garter under his left knee. Ladies of the Garter wear their garters above their left elbows. (Buckled shoes, however, are not correct wear with white tie; rather, 'court pumps' (low-cut patent shoes with black bows) may be worn - either with breeches or with trousers.)
Other than opera pumps (which can have pinched or flat bows), patent or highly-polished calf leather Oxfords (with or without toe-cap seam) are correct to wear with white tie, especially with black satin ribbon laces. In the past, other types of shoes have been worn but are now rarely seen; these include patent button boots (with black wool or silk galoshes) and Chelsea boots (sometimes with bows). The socks are of black or midnight blue silk or fine cotton. The trend to wear coloured socks with white tie is incorrect because it draws unnecessary attention to the feet, distorts the run of black from waist to toe and is illogical to the black-white colour scheme.
Although female dress is not as formally codified as that of men, women are expected to wear full-length dresses such as ball gowns. Dresses with lengths above the ankle (such as cocktail or tea-length dresses) are frowned upon and considered inappropriate. Depending on the formality of the event, bare shoulders may or may not be acceptable. Shawls and long gloves are common accessories. Women's gloves should be white and upper-length/opera-length, and are never taken off until the woman is seated at a table. They are to be put on again after the meal is finished. At the most formal debutante balls, ball gowns are often required to be white. At hunt balls, ball gowns are often required to be black, white, silver or gold.
Where state decorations are worn, it will usually be appropriate for royal and aristocratic women to wear tiaras.
Military dress uniform is the appropriate military uniform for white tie occasions, though mess dress is also sometimes used, as not all nations have two distinct classes of formal evening uniforms. At hunt balls (run by fox hunting clubs), members who are entitled to do so may wear a scarlet tailcoat. This hunt attire is colloquially known as "drinking pinks", to distinguish it from the "pinks" intended to be worn while riding. A hunt ball invitation in America would generally specify the dress code as "black tie, or scarlet if convenient".
Certain clergymen wear, in place of white-tie outfits, a cassock with ferraiolone, which is a light-weight ankle-length cape intended to be worn indoors. The colour and fabric of the ferraiolone is determined by the rank of the cleric and can be scarlet watered silk, purple silk, black silk or black wool. For outerwear the black cape (cappa nigra), also known as a choir cape (cappa choralis), is most traditional. It is a long black woollen cloak fastened with a clasp at the neck and often has a hood. Cardinals and bishops may also wear a black plush hat or, less formally, a biretta. In practice, the cassock and especially the ferraiolone have become much less common and no particular formal attire has appeared to replace them. The most formal alternative is a clerical waistcoat incorporating a Roman collar (a rabat) worn with a collarless French cuff shirt and a black suit, although this is closer to "black-tie" than white-tie.
Some invitations to White Tie events state that National costume or National dress may be substituted for the strictly regulated dress code of White Tie.
As a specific example of national costume, Scottish National costume/Scottish National dress may be chosen by someone attending as the representative of Scotland on state business.
As with other forms of ethnic dress and National costume, there is no direct equivalent to White Tie in Scottish National Dress.
- The chief dress code components for White Tie, as stated above, would still apply, with the kilt substituted for the trousers.
- The Prince Charlie Coatee or one of the doublets would be worn instead of the evening tail coat.
- The White plain stiff-fronted cotton shirt with white stiff wing collar, white pique cotton bow tie and white low-cut pique waistcoat would be the same if the Prince Charlie Coatee is worn. If a Doublet is worn a white lace jabot and cuffs are appropriate substitutes for the bow tie.
- Black court pumps (with black silk bows), patent Oxfords, or patent buckle brogues.
- Tartan, diced or black silk kilt hose.
- Silk garter flashes or garter ties
- Sterling Silver-mounted sporran in sealskin, fur or hair with a silver chain belt
- A Sterling Silver-mounted, sgian-dubh may be worn tucked into the top of the hose when appropriate.
- The Scottish Dirk hung from a dirk belt is optional when appropriate.
- A fly plaid in Tartan matching the kilt, attached with a Sterling Silver plaid brooch is optional.
- A Balmoral bonnet with badge is sometimes substituted for the top hat if out of doors.
- Tartan trews are sometimes substituted for the kilt, kilt hose and sporran. 
These are the usual occasions when white tie would be expected to be worn. Almost always, the dress code would specify 'white tie' or 'full evening dress', with or without decorations depending on whether it is a state event. Notwithstanding these usual events, private parties may demand or allow people to wear white tie.
- State dinners (e.g. dinners with visiting heads of state)
- Some may balls and commemoration balls at the old universities, such as Oxford and Cambridge
- Very formal evening weddings
- Hunt balls
- Carnival balls
- Caledonian Reeling Balls such as the Skye and Oban Balls and Reeling Balls at universities including amongst others Durham, Edinburgh and St Andrews
- CUCA & OUCA Chairman's Dinners & Termly Dinners
- Cambridge University Heraldic and Genealogical Society formal dinners
- Public Business Meetings of the Oxford Union by Junior Officers
- Some balls during the London Season
- The Lord Mayor of London's Mansion House Banquet (although Gordon Brown famously ignored the dress code whilst he was Chancellor of the Exchequer.)
- The most formal banquets in the City of London of the Livery Companies at either the Mansion House, the Guildhall or in a Livery Hall.
- International Standard and American Smooth ballroom dance competitions
- Christmas parties where the dress-code is "red carpet ready"
The dress coat is also part of other related codes, such as civilian day court dress in the royal court (in the United Kingdom). However, these alternatives are now being replaced by standard white tie for formal state occasions, such as for ambassadors at the State Opening of Parliament.
In the United States white tie has been replaced by black tie for many formal occasions such as evening weddings, the Academy Awards and even presidential inaugural balls. It is still occasionally seen at:
- very formal balls and cotillions
- very formal evening weddings
- some Masonic events
- some opera or ballet galas or fundraisers
- formal dinner night on some cruise ships
- In addition, musical conductors and members of an orchestra or symphony playing classical music often are dressed in white tie, as well as many college-level choirs and glee clubs, and the occasional barbershop quartet.
In Finland and Sweden as well as the Netherlands many academic traditions (disputations, commencement ceremonies, and academic balls) still require white tie, even during the daytime. In these countries, academic traditions require a black waistcoat for daytime ceremonies. If no ladies without doctoral degree are present, it is customary to wear a black waistcoat even in the evening. For formal academic balls of student unions, student nations, and other student organizations, couleur is worn with the white tie.
In some universities (most notably Aalto University), doctoral regalia includes a black tailcoat with facings bearing the insignia of the university, embroidered in gold or silver. Doctors from these universities may wear this regalia at all occasions requiring white tie. On the other hand, doctoral swords are not usually worn during normal white-tie occasions. Doctors may wear their doctoral headgear instead of opera hats even for non-academic occasions.
In Japan, white tie, or a variant combining the bow tie with a black lounge suit, is worn for school graduation ceremonies by the school principal and the teachers of the graduating students; and also for certain government functions. White tie is worn at the Imperial Court for ceremonies.

- Clerical dress (by persons in holy orders)
- Clerical dress (by clerks etc. in Parliament)
- Court dress (in courts of law)
- Court dress (in the royal court)
- Academic dress (in the older universities such as Oxford, Dublin Cambridge, Durham, Edinburgh, St David's College and St Andrews)

The description does not say that the waistcoat should not extend below the fronts, but the plate illustration of the New Style Court Dress clearly shows that the waistcoat does not extend below the fronts so it is implied that the waistcoat should be worn in this way and is relevant to the full evening dress as it is cutaway the same way as the New Style Court Dress coat given the New Style Court Dress essentially is based slightly on full evening dress of the time.
