Every style at ProStratum is made to order, so a little extra care in choosing your size goes a long way.

Kids' Sizing

Kids' and baby sizing runs by age (2T–14) rather than chest/waist measurements. Please check each product's size chart for the exact height and weight range for that age label.

How to Measure

Chest/Bust: Measure around the fullest part of your chest, keeping the tape level.
Waist: Measure around your natural waistline, at the narrowest point.
Hip: Measure around the fullest part of your hips.

Still Unsure?

If you're between sizes, we generally recommend sizing up for a relaxed fit or sizing down for a fitted look. Reach out to us any time if you have questions before you order — we're happy to help you pick the right size.
