Fancy dress businesses sell or hire costumes and accessories for parties, celebrations, performances and other themed events. Their ranges commonly include outfits for adults and children, such as character, historical, film-inspired, occupation and seasonal costumes. Customers may also find wigs, masks, hats, make-up, jewellery, props and other items to complete an outfit. Some shops specialise in costume hire, offering garments for a set period and advising on sizing, care and return arrangements. Others focus on sales, with options ranging from complete outfits to individual accessories. Stock may vary throughout the year, with costumes and decorations for occasions such as Halloween, Christmas, school events and themed parties. Certain businesses also provide costume alterations or help customers assemble an outfit from available items.
