Most wedding dress stores carry samples in just one or two sizes for brides to try on in-store. Even if these dresses are not in your size, bridal consultants will help you visualize how the same dress in your size would look. If you like what you see, the boutique will be able to order your wedding dress in any size offered by the manufacturer. Therefore, you need not worry if your exact dress size is not available in the store. You can still order it in your closest size if you like the design.
