We at Costumes4less.com want the costumes you choose, to fit well, so that these may be fully enjoyed. Please check the product description in addition to looking at this chart. Costumes, unlike street clothes, are not made in every size. Rather, these are designed and constructed so that one size can accommodate a variety of sizes. Many have elastic waistbands and utilize stretch fabrics.
If you or your child are in an in-between size or if you are unsure about size, we usually recommend that you buy one size larger.
