A corsetmaker is a specialist tailor who makes corsets. Corsetmakers are frequently known by the French equivalent terms corsetier (male) and corsetière (female). Stay-maker is an obsolete name for a corsetmaker. The word corset replaced the word stays after the Great Exhibition in 1851, because a prizewinning type of French stay was called the Hygienic Corset.
The best corsetmakers are highly skilled tailors with a knowledge of anatomy that enables them to make well-fitting, long-lasting corsets. Corsetmakers who reproduce historical styles must be familiar with historical fashions and costumes that span centuries of history.
Individual corsetmakers often favour a certain style, and frequently have differing theories and opinions about the physical impact and benefits of various corsets, thereby influencing their corset design and creation.
