Swim Leggings – Dream Weaver
Every child is unique, so our age sizing is intended as a guide only. For the best fit, we recommend comparing the garment measurements in our size chart with a swimsuit that already fits your child well.
Girls Swimwear
One pieces, bikinis and swim sets. Sizes 1 to 16. All measurements are taken from the garment laid flat and unstretched, in centimetres. The easiest way to choose is to measure a swimsuit that already fits your child well and compare it with the chart.

Measure what fits
Lay a swimsuit your child wears now on a flat surface and measure it unstretched. It's more reliable than measuring a wriggling child.
Allow for stretch
Our swim fabric has four-way stretch and gives around 2–4 cm when worn, so a snug flat measurement is fine.
Between sizes?
Styles can vary by 1–2 cm. If you're unsure, size up for extra length and a longer season of wear.
