During a sample sale, bridal boutiques sell floor samples from previous collections at discounted prices. These dresses will cost several hundreds of dollars less than the original just because they are out of the original packaging and tried on. Dresses are sold on a first-come, first-sold basis during sample sales. It is a good idea to call the boutique in advance and find out if you need an appointment to attend the sale. The boutique will be crowded during the sale, which makes it impractical to try on too many dresses. You will have to quickly decide if you find a dress you like and buy it right away.
