A Costume Designer is a professional responsible for creating the clothing and accessories worn by characters in film, theater, and television. They work closely with directors and producers to understand the vision of the production and ensure that the costumes reflect the time period, setting, and personality of each character. Costume Designers often research historical styles and trends, sketch designs, and select fabrics. They may also collaborate with other departments, such as set designers and makeup artists, to create a cohesive look for the production. Their work plays a crucial role in storytelling and character development.
