Dress shirt
A dress shirt, button shirt, button-front, button-front shirt, button-down, button-down shirt, or button-up shirt is a garment with a collar and a full-length opening at the front, which is fastened using buttons or shirt studs.
Dress shirts are normally made from woven cloth, and are often accompanied by a jacket, collar sleeve, and tie, for example with a suit or formalwear, but shirts are also worn more casually.
In British English, "dress shirt" means specifically the more formal evening garment worn with black- or white-tie. Some of these formal shirts have stiff fronts and detachable collars attached with collar studs.
Traditionally dress shirts were worn by men and boys, whereas women and girls often wore blouses or, sometimes, known as chemises. However, in the mid-1800s, they also became an item of women's clothing and are worn by both sexes today.
The term "button-down" refers to a type of shirt which has a collar fastened down by buttons, but is sometimes used in error to apply to all dress shirts.
