Measuring Guide

How To Measure

There are 3 key areas to measure when fitting swimwear. To achieve an accurate measurement we recommend wearing minimal clothing when measuring and holding the measuring tape straight and parallel to the floor.

Chest: Standing normally, measure around the fullest part of your chest.

Waist: Measure your natural waist, just above your hipbone.

Hips: Putting your feet together, measure the fullest part of your hips.

Expert Tips

Children’s sizing usually corresponds with a child’s age.
