Young Girl Wearing A Tight Corset

The word corset is derived from the Old French word corps, the diminutive of body, which itself derives from corpus - Latin for 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, respectively), or sometimes simply a corsetmaker.
The word corset came into general use in the English language in 1785. The word was used in The Ladies Magazine to describe a "quilted waistcoat" called un corset by the French. The word was used to differentiate the lighter corset from the heavier stays of the period.
