The four ways to add coverage
Modesty is a spectrum. Pick the pieces that match what matters to your family.
Higher neckline & back
A scoop or high-neck one-piece covers the chest and back far more than a typical tankini.
Swim shorts or skirt
Boardshort-style bottoms for active days, a skirted brief for casual ones. Both add real lower-body coverage.
Long-sleeve rash guard
Full arm coverage plus UPF 50+ sun protection. The most coverage in a single piece.
Longer torso length
A suit cut long enough to actually reach stays modest when she moves. This is where extended sizes matter most.

Modest tween swim: questions answered
What makes a tween swimsuit modest?
Modest swimwear adds coverage where standard suits cut away: a higher neckline, fuller chest and back coverage, longer torso, and bottoms that cover more like swim shorts or a skirted brief. Rash guards add sleeves. Modesty is a spectrum, so decide which areas matter to your family and match the style to that.
Swim shorts or a swim skirt for tweens?
Both add coverage; it comes down to activity. Swim shorts stay put for active swimming, sports and water parks. A swim skirt with attached briefs reads dressier and suits casual pool days. Many tweens own one of each. Lands' End and Lime Ricki carry both in extended sizes.
Are rash-guard sets a good modest option?
Yes, one of the best. A long-sleeve rash guard plus swim shorts gives near-full coverage and UPF 50+ sun protection in one outfit, which parents love for long beach and pool days. Cabana Life, Snapper Rock and SwimHer all make rash-guard sets in tween and extended sizes.
Can I get modest swimsuits in size 18 or plus?
Yes. Lands' End and SwimHer both carry modest, high-coverage styles into girls' plus and teen sizes, and Lime Ricki bridges girls' into women's sizing. For exact size-18 measurements and stock, start with our girls size 18 guide, then filter for high-coverage styles here.
