Shop Girls' Swimsuits for Every Age & Activity
Choosing Girls' Bathing Suits
The right girls' bathing suit depends on how she uses it. For swim lessons and pool play, comfort and a secure fit matter most. For the beach and water parks, sun protection and quick-dry fabric help. For swim team, chlorine resistance and a race-ready cut come first. Match the suit to the activity, then narrow by size and coverage.
Girls' Swimsuit Styles
Girls' swimsuits come in a few core shapes. One-piece suits give the most coverage and stay secure for active swimming, which makes them the standard for lessons and swim team. Two-piece styles, including tankinis and bikinis, make bathroom breaks easier and let girls mix tops and bottoms for the right fit. Rash guard sets pair a short or long sleeve top with matching bottoms for extra sun coverage. Browse girls' one-piece swimsuits for everyday and team use, or girls' two-piece swimsuits for tankini and bikini sets.
Sizing for Little Girls and Teens
Girls' swimwear includes toddler and little girls' sizes as well as big girls' and teen fits. Little girls' suits size by age and often add snap closures and adjustable straps. Big girls' and teen swimsuits move toward adult-style cuts with more coverage options and longer torsos. Check the size chart on each suit, since fit varies by cut. A suit should feel snug when dry, because swimwear fabric relaxes slightly in the water.
Swimsuits for Swim Team and Lessons
Girls who swim laps or compete need a suit that resists chlorine and stays in place through starts and turns. Practice and competition suits use tighter, chlorine-resistant fabric and a racerback or cross-back strap design that frees the shoulders. For meets and daily practice, see girls' competition swimsuits. For lessons and casual swimming, a comfortable one-piece or tankini set works well.
Sun Protection and Fabric
Many girls' bathing suits and rash guards add UPF 50+ sun protection, which blocks most UV rays and helps on long beach and pool days. Chlorine-resistant polyester and PBT blends hold color and elasticity far longer than standard nylon, so a team suit can last a full season of practice. Quick-dry fabric keeps girls comfortable between sessions at the pool or water park.
Coverage and Fit
Coverage is a personal choice. Rash guard tops and swim shirts add sun and skin protection for active kids. Higher-cut bottoms and full-coverage one-pieces stay secure during diving and water slides. For two-piece shoppers who want to mix sizes, separate tops and bottoms give a better fit than a fixed set. Parents shopping for siblings can also browse boys' swimwear for matching pool and beach trips.
