A draper usually works on fashion designs or costumes for theater and films. Typically, a draper works with the sketches of a fashion or costume designer, creating the outfits by draping the clothing over a form. You then oversee the necessary cutting and sewing. This type of fitting is an alternative to using measurements and patterns, and allows the designer to see the fashion piece before final construction. In broader terms, the duties of a draper are to act as the designer’s representative during tailoring and assist in the production of clothing/costumes.
