The wardrobe supervisor is responsible for overseeing all wardrobe related activities during the course of a theatrical run or film shoot. The modern title "wardrobe supervisor" has evolved from the more traditional titles of "wardrobe mistress/master" or "mistress/master of the wardrobe". The wardrobe supervisor may be present at some production meetings and fittings, their primary responsibilities generally begin at the load-in stage of a production and during prep of a film. At load-in physical custody and responsibility for the costumes shifts from the costume designer and shop staff to the wardrobe supervisor.
