A nurse uniform is attire worn by nurses for hygiene and identification. The traditional nurse uniform consists of a dress, apron and cap. It has existed in many variants, but the basic style has remained recognizable.
The first nurse uniforms were derived from the nun's habit. Before the 19th century, nuns took care of sick and injured people so it was obvious that trained lay nurses might copy the nun's habit as they have adopted ranks like "Sister". One of Florence Nightingale's first students (Miss van Rensselaer) designed the original uniform for the students at Miss Nightingale's school of nursing. Before the 1940s minor changes occurred in the uniform. The clothing consisted of a mainly blue outfit. Hospitals were free to determine the style of the nurse uniform, including the nurse's cap which exists in many variants.
In Britain, the national uniform (or simply "national") was designed with the advent of the National Health Service (NHS) in 1948, and the Newcastle dress.[clarification needed] From the 1960s open necks began to appear. In the 1970s, white disposable paper caps replaced cotton ones; in the 1980s, plastic aprons displaced the traditional ones and outerwear began to disappear. From the 1990s, scrubs became popular in Britain, having first appeared in the USA; however some nurses in Britain continue to wear dresses, although some NHS trusts have removed them in favour of scrubs as in many other countries.
Standard nurse's uniform 
Historically, a typical nurse uniform consisted of a dress, pinafore apron and nurse's cap. In some hospitals, however, student nurses also wore a nursing pin, or the pinafore apron may have been replaced by a cobbler style apron. This type of nurse's dress continues to be worn in many countries.
Alternative nurse uniforms 
- A tunic-style top and dark blue trousers that are optimally designed to prevent cross-infection, the colour of which depends upon the grade (or, more recently, band) of the nurse—the colour varies between NHS Trusts. The tunics often feature piping around the edges of the uniform.
- A dress in the same colour as the tunic-style top.
Traditional uniforms remain common in the Third World, but in Western Europe and North America, so-called "scrubs" or tunics have become more popular. "Scrub dress" is a simpler type of uniform, and is almost always worn in operating rooms and emergency rooms.
Nurse uniforms vs scrubs 
Beginning in the 1990s, and until the present time, the traditional nurse uniforms have been replaced with the "new" scrub dress in some countries. Most hospitals in the USA and Europe argue that the scrub uniform is easier to clean than the old nurse uniforms. The nurses who wear the uniforms are divided into two camps:
- Those who prefer the new scrubs; disliked the old white nurse dress uniforms.
- The nurses who liked the old white nurse dress uniforms; they argue that nurses who wear scrubs are seen by the patients as cleaners or surgeons and cannot be identified as nurses.
In many parts of the world, nurses continue to wear a white uniform consisting of a dress and cap. The traditional white uniform for male nursing staff is now going out of fashion, excepting for student nurses. A tunic of either the dental surgeon style or a v neck with a collar is very often used. The colours vary with grade, area of work, and hospital; however, the male equivalent of sister (that is, charge nurse) tend to be shades of blue or dark green: often, this is the only colour to be recognised by the public as signifying a person in authority.
Nursing Jewellery 
Nurses were actively discouraged from wearing jewellery which might distract from their purpose and get caught on patient skin during care activity. A fob watch or pendant Watch was once considered synonymous with nursing. The fob watch freed the nurses hands for client care and prevented the wrist watch becoming a vector for disease. Watches were sometimes given as a token right-of-passage gift from parents to young nurses, who were making the transition into nurses quarters and lived away from home for the first time.
