Long Sleeve One Piece Swimsuit with Side Ties
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.

Set sail with our Girls Long Sleeve One Piece with Side Ties. Featuring puffy long sleeves and a classic boat neckline, this swimsuit offers sun protection with a touch of charm. The easy-zip back and adjustable side ties add both convenience and playful detail.
