Buying Guide: How to Choose a Period Swim Suit for Tweens
- Protection Level: Look for four-layer designs or built-in leakproof gussets. Consider how much protection you need for heavy flow days or light discharge days.
- Fit and Rise: Choose among low, mid, or high-rise options to find comfort and coverage. For active swimming, a higher rise often stays in place better.
- Fabric and Care: Prioritize UPF 50+ fabric and quick-drying materials. Check washing instructions to preserve leakproof layers and odor-control lining.
- Style and Coverage: One-piece, racerback, and two-piece designs offer different coverage levels. Consider the tween’s activity level and preferred style when selecting.
- Sun Protection: UPF protection helps guard skin during extended pool or beach days. Anti-chlorine fabrics tend to last longer in chlorinated water.
- Sizing: Because bodies differ, refer to size charts carefully. For tweens, sizing often runs smaller and may require hero sizing up or down for a snug fit.
- Care Tips: Rinse after swimming, avoid fabric softeners, and dry flat to maintain elasticity and leakproof layers.
