Old prom dresses can be sold online on auction sites or at consignment shops, particularly those specializing in prom dresses, homecoming dresses and other special event attire. Schools sometimes have prom dress sell-back events. Prom dresses can usually sell online or in stores year-round, but it is important to market the prom dress properly in order to successfully sell it.
When selling a prom dress online, it helps to provide descriptive information such as the brand name, measurements, multiple photos and some indication of the product's condition. Clothing should also be cleaned and checked for tears. Pricing on prom dresses can vary, but styles that are about 2 to 3 years old typically sell best.
