Size Guide
Children of the same age vary a lot, so measuring is the most reliable way to get the fit right first time.
How to measure
- Chest: measure all the way around the chest, under the armpits.
- Length: measure from the top of the strap.

Getting the fit right
- Between sizes? Size up. Swimwear should be snug but never tight, and a little growing room means it lasts a second summer.
- The age column is a guide only. Her measurements are what determine the fit - always measure if you can.
- Not every size is available in every style. The sizes you can choose on each product page are the sizes we currently stock in that design.
Still unsure? Email contact@maegirls.com with your daughter’s measurements and the style you’re looking at, and we’ll tell you which size to order.
