A dresser works in a theatre to help an actor get in and out of a costume for different scenes. In this career, you can also work with a designer to assist models during a fashion show. In either role, your responsibilities include handling and storing the wardrobe between uses. You set out everything that the actor is going to use between scenes. Your duties also involve inspecting the items and sending them for alterations and repairs as needed. You often make adjustments on the spot to ensure a proper fit, but you are not responsible for making major alterations to the piece.
