There are several jobs in a variety of industries that involve custom sewing. As a tailor, costume designer, or wardrobe assistant, you work in a theater or as part of the crew on a film or tv show. Your duties and responsibilities include costume design and sewing, and you are in charge of fittings, during which you alter or repair costumes so that they are appropriate for your actors. You work with actors, directors, writers, and producers to understand your characters, and you do research to inform your designs. In some roles, you also repair and maintain masks, wigs, and other accessories, so you need to be knowledgeable about different textiles and materials that are used on stage and on the screen.
