Steaming out wrinkles from a dance costume is a great way to get it looking its best before a show. To do this, start by laying the costume flat on an ironing board. Then, fill a steamer with hot water and hold it about 5-8 inches away from the fabric. Move the steamer over the fabric in a slow, sweeping motion to allow the steam to penetrate the fabric. You may need to pass over the fabric several times to get the wrinkles out. When finished, hang the costume up and allow it to air dry.
