Corsetmakers are frequently known by the French equivalent terms corsetier (male) and corsetière (female).
The best corsetmakers are highly skilled tailors with a knowledge of anatomy that enables them to make well-fitting, long-lasting corsets.
For short-term use, e.g. used for a special event such as a wedding, a corset will be worn briefly and so is not subject to wear, therefore need not be of the highest quality of construction.
For long-term use, e.g., by tightlacing or waist training, corsets must be made to exact standards and are best custom-fitted and designed for the individual wearer.
Some custom-made gowns have corsets built into the design; a talented dressmaker may also be a skilled corset-maker.
