Leotard Fit: Size Up

ACA leotards have a close, fitted silhouette and run smaller than our sets and unitards. Choose one size up from your usual ACA set or unitard size.

How to Measure

• Bust: Measure around the widest part of the chest.
• Waist: Measure around the smallest part of the midsection.
• Hips: Measure around the widest part of the hips.
• Inseam: Measure from the crotch to the ankle.
• Girth: Start at the top of one shoulder, bring the tape down the front, through the legs, and back to the same shoulder.

If your measurements fall between sizes, choose the larger size for a more comfortable fit.
