A corset is a support garment commonly worn to hold and train the torso into a desired shape, traditionally a smaller waist or larger bottom, for aesthetic or medical purposes (either for the duration of wearing it or with a more lasting effect), or support the breasts. Both men and women are known to wear corsets, though this item was for many years an integral part of women's wardrobes.
Since the late 20th century, the fashion industry has borrowed the term "corset" to refer to tops which, to varying degrees, mimic the look of traditional corsets without acting as them. While these modern corsets and corset tops often feature lacing or boning, and generally imitate a historical style of corsets, they have very little, if any, effect on the shape of the wearer's body. Genuine corsets are usually made by a corsetmaker and are frequently fitted to the individual wearer.
The word corset is a diminutive of the Old French word cors (meaning "body", and itself derived from the Latin corpus): the word therefore means "little body". The craft of corset construction is known as corsetry, as is the general wearing of them. (The word corsetry is sometimes also used as a collective plural form of corset). Someone who makes corsets is a corsetier or corsetière (French terms for a man and for a woman maker, respectively), or sometimes simply a corsetmaker.
In 1828, the word corset came into general use in the English language. The word was used in The Ladies Magazine to describe a "quilted waistcoat" that the French called un corset. It was used to differentiate the lighter corset from the heavier stays of the period.
While the original purpose of stiffened undergarments was founded in the avoiding of creasing to costly, highly adorned outer garments, the most common and well-known use of corsets is to slim the body and make it conform to a fashionable silhouette. For women, this most frequently emphasizes a curvy figure by reducing the waist and thereby exaggerating the bust and hips.
