These measurements are when the item is lying flat and not stretched. Measure an existing pair of well-fitting swimmers for reference.

Otherwise, the measurement indicated is the minimum size and when wearing can stretch up to 2-4cm while still fitting comfortably.

Measurements can be slightly under or over the given measurement; this is an average guide, as different styles vary 1-2 cm between styles. 

Our sizes are based on Australian standard children's sizing, which coincides with the child's age. Though, it should only be used as a guide only.
