They often represent characters from movies, books, or history, allowing wearers to engage in imaginative play. Common themes include superheroes, princesses, animals, and historical figures, making them popular for occasions like Halloween or themed parties. These costumes can be purchased from stores or made at home using various materials. Accessories such as hats, masks, and props often accompany the costumes to enhance the overall look. Dress-up costumes encourage creativity and role-playing, helping individuals express themselves in fun and engaging ways.
