Girls Swimwear FAQ

What sizes do girls swimsuits come in?

Girls swimwear here runs from size 2 to 16, depending on the brand. Hatley swimsuits and tankini sets go from 2Y or 3Y up to 12Y, Deux par Deux suits run 2/3 to 13/14, and Mayoral covers 2Y to 10Y. For older girls, Under Armour swim sets go up to 16Y.

Should I choose a one-piece, a two-piece or a rashguard swimsuit for my daughter?

It mostly comes down to coverage and ease. Two-pieces and tankinis are quicker for bathroom breaks, while rashguards cover more skin: Hatley makes a short-sleeve one-piece rashguard with a front half zipper, and Petit Lem and Miles The Label offer long-sleeve swimsuits, many in 2Y to 6X.

Which girls swimsuits list UPF sun protection?

Several do, and the rating differs by brand. Hatley one-pieces and tankini sets are listed as UPF 50+, Deux par Deux two-piece swimsuits are listed as UPF 50+, and Under Armour girls' sets list UPF 30+ for covered areas. A swimsuit only covers part of the body, so plan on shade, a hat and sunscreen too.

What are girls swimsuits made of, and how do I wash them?

Hatley swimsuits are 88% nylon and 12% spandex. Deux par Deux uses 85% recycled polyester (REPREVE) with 15% elastane and recommends a cold machine wash and hanging to dry, with no tumble dryer. Under Armour sets are 85% polyester and 15% spandex, washed cold on a gentle cycle. Rinsing suits in fresh water after the pool is a good habit.

What else should we pack for beach days and swim lessons?

Deux par Deux makes terry cloth and mesh beach dresses that slip over a swimsuit, plus swim caps in sizes 2/6 and 7/14. Add a beach towel, a brimmed sun hat from kids hats and caps, and a dry change of clothes such as girls shorts for the ride home.
