Size Guide

Swim Collection 2026

All measurements are in centimetres, taken from the swimsuit laid flat.

  • ½ Chest is measured across the front only. Double it for the full measurement around.
  • Easiest way to check: lay a swimsuit that fits your child well now flat on a table, measure it, and compare with the charts below.
  • Swimmers should feel snug when dry. They relax a little in the water.
  • Between sizes? Size up.
