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

Girls’ swimwear: Our girls’ styles have a more fitted feel. If your little one is between sizes or nearing the top of an age bracket, we recommend sizing up for comfort and room to grow.

Boys’ swimwear: Our Milo and Zeke shorts are designed with a slightly roomier fit through the waist. If your little one is between sizes or has a smaller waist, we recommend sizing down for the best fit.

Arlo rashie: The Arlo rashie fits true to size through the body. We recommend sizing up.

Fit can vary slightly between styles and fabrics. If you’re ever unsure, feel free to reach out - we’re always happy to help with sizing.
