Just like furniture stores, bridal shops have samples too! Bridal stores often have samples of wedding dresses (usually size 8 or 10) for brides to try on a selection of styles before they buy. Sometimes the retailers will sell the dresses if they are still in good condition, so be sure to ask your local bridal boutiques about them! Wedding gown samples can also be bought at trunk shows.
