Dresser (theatre)
A dresser is a theatrical stagehand who is involved with maintaining costume quality at each performance. They are hired by either the director, producer, or wardrobe supervisor. They report directly to the wardrobe supervisor and are usually paid by the hour.
Dressers are responsible for assisting cast members with costume changes backstage. They are often used to assist primarily with quick costume changes, where a character exits and must enter again very quickly wearing a different costume.
