Classy Bride's short robes run true to size, but they are short. They are available in 4 sizes: S/M, L/XL, 1X/2X, and 3X/4X. We always recommend anyone taller than 5'6" go up to the L/XL. Even slender builds would appreciate the 2 extra inches the L/XL provides. Our short bridesmaids robes are perfect for bridal parties that require a range of sizes and are mostly 5'9" or under.
