Buying Guide

Prioritize UPF protection

Look for swimsuits labeled UPF 50+ to reduce UV exposure for sensitive skin during extended outdoor play

Check fabric and lining

Choose blends with nylon or polyester and a soft lining for chlorine resistance, quick drying, and comfortable wear

Consider fit and sizing options

Pick adjustable or true-to-size cuts and consult size charts for toddler versus older-girl proportions to avoid rebuys

Look for secure closures and straps

Wide straps, ruffle reinforcement, or modest back coverage help keep suits in place during swimming and activity

Evaluate care instructions

Prefer machine-washable suits that recommend gentle cycles and line drying to preserve color and elasticity
