This size chart is to help determine your leotard size. If any of your measurements are on the borderline between two sizes, you can pick the smaller size for a tighter fit or the larger size for a looser fit. If your chest and waist measurements correspond to two different sizes, you should order the one which is indicated by the measurement of your chest. The same is true for the waist and hips, order to accommodate for the hips. Please do not hesitate to reach out to us with any questions if you are still unsure of what size to order. Also, if we do not show a size listed here that works for you, email us and we can work with you to make one!
