FAQ

We recommend checking our detailed size guide for each designer, as independent brands can vary slightly in their cuts. If your baby toddler is between sizes or wears a thicker reusable swim diaper, it is usually best to size up to ensure complete comfort and freedom of movement.
A upf 50 sun protection rating means the fabric blocks out 98% of harmful UVA and UVB rays, providing an excellent physical barrier for your baby's delicate skin. This standard is crucial for young children, ensuring they remain shielded during prolonged outdoor play alongside regular sunscreen application.

Yes, standard swim trunks and boardshorts do not have integrated containment, so a disposable or reusable swim diaper should be worn underneath. Some of our one-piece options and baby swimsuits feature built-in diaper covers or extra room designed specifically to accommodate them comfortably.
To preserve the elasticity and vibrant colors of the fabrics, rinse the swimwear in cool, fresh water immediately after use to remove chlorine or salt. We advise washing them on a gentle cycle with a mild detergent and laying them flat to dry in the shade rather than using a tumble dryer.

Absolutely. Our collection is intentionally curated to allow parents to mix and match different tones, prints, and styles seamlessly. Pairing a solid long sleeve rash guard with striped or patterned swim shorts is a wonderful way to build a versatile and stylish beach wardrobe.
