Two-Piece Swimwear

Shop kids two-piece swimwear at MOMASONG for beach holidays, pool days, swim lessons and everyday water play. This collection includes two-piece swim sets with coordinated tops and bottoms, practical coverage and playful designs for girls and boys. Two-piece swimwear makes changing easy and gives children comfortable freedom to move, whether they are playing by the pool, exploring the beach or enjoying a family vacation.

Choose from short-sleeve swim sets, long-sleeve rash guard sets, zip-up tops with matching bottoms and other coordinated two-piece styles. Depending on the design, features may include soft lining, stretch fabric, elastic waistbands, secure hems and quick-drying construction. Please review the individual product page for the exact fabric composition, lining, closure details and sun-protection information. UPF 50+ applies only to products specifically labeled with that rating.

For a confident retail purchase, compare your child’s measurements with the size chart shown on the product page. A two-piece set should fit securely while allowing comfortable movement in the shoulders, waist and legs. Check whether the product is designed with a close fit or a more relaxed fit, and consider the child’s preferred coverage when choosing between short-sleeve, long-sleeve or standard swim-set styles. This collection is for children’s ready-to-wear swimwear; it does not include infant or baby swimwear.

Care for swimwear by rinsing it with clean water after use and air drying it away from direct heat. Avoid bleach, fabric softener and rough surfaces that may pull the fabric. Always follow the care instructions listed on the specific product page to help maintain color, stretch and shape.
