The flower girl robe is a one-size-fits-most item, designed to fit U.S. child sizes 4T - 6X. Unfortunately, there are no additional size options to select when adding the robe to your cart. For more detailed sizing information, please refer to the sizing chart found in the 'Sizing Details' section of the product page. If you are looking for larger sizing, we also offer junior bridesmaid and women’s sizes, which can be found in our robe category.
