Every little one grows in their own unique way, and no two bodies are the same. This guide is here to help you choose the best fit, but please use it as a reference only.

Our girls’ swimwear fits true to size.

Our boys’ Milo and Zeke shorts run slightly roomier in the waist. If your mini is between sizes or has a smaller waist, we recommend sizing down for the best fit.

Our unisex Arlo rashie fits true to size, with a snug neckline for sun safety. We generally recommend choosing the larger size for extra comfort, especially if your little one prefers a looser neck or will wear it over our frill or detailed Suki pieces.

Fit can vary slightly between styles and fabrics.

If your little one is nearing the end of their age bracket, we recommend sizing up.
