Girls' Blue Swimwear

For active swimming, two-piece sets and tankinis offer more flexibility and easier movement than most one-pieces, especially when paired with adjustable straps and waistbands. Look for nylon-spandex blends with 4-way stretch to give room for growth and full mobility while in the water.

Rashguards and surfer suits with UPF 50+ fabrics block about 98% of UV rays, making them the best choice for extended sun exposure. Coolibar rashguards are a good example of a protective style, and long-sleeve options give extra arm coverage for surfing or beach play.

Try to pick stretchy fabrics like nylon-spandex blends and consult the size chart for bust, waist, and hip measurements so the suit fits now and after a growth spurt. Sizes range from 2T-16Y or XS-XXL, and checking torso length on one-piece suits will help ensure the coverage stays comfortable.

Nylon-spandex blends and polyester are common for quick-dry performance and durability, with many swimsuits offering chlorine resistance up to 200 hours for frequent pool use. Also consider flatlock seams and reinforced stitching to prevent chafing and extend the life of a well-used suit.

Yes. Mix-and-match sets let you pair different sizes and styles—like crop tops with boy-short bottoms—to get the right fit and modesty level, and brands like RuffleButts make coordinating reversible prints and ruffle details easy. Toss on a cover-up or skirt for a smooth transition from water to sand or casual outings.
