Costume shops are retail stores that specialize in selling costumes and accessories for various occasions. These shops often cater to events like Halloween, theatrical performances, and theme parties. They typically offer a wide range of costumes, from classic characters to modern trends, along with props and makeup to complete the look. In addition to selling costumes, many costume shops also provide rental services. This allows customers to borrow costumes for a limited time, which can be a more economical option for those who only need a costume for a short period. Some shops may also offer custom costume design services for unique requests.
