Please be sure to measure your child carefully. If there is a question on size (borderline between two sizes) it's best to go with the bigger size and plan to alter it if it is too big. If the costume is too small, it is much more difficult to remedy this issue. Remember that your little ones will do some growing between now and the recital, so keep this in mind as you select your size. After selecting your size click on the "order now" button to place your order and pay online.
