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 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.
