Best L Girls Athletic Swimwear in 2026

Yonique has hit a sweet spot for anyone needing versatile, modest swimwear that doesn't sacrifice a sporty aesthetic. This three-piece set is a total game-changer because it offers actual modularity. You can wear the full tankini combo for extra stomach coverage or strip it down to the criss-cross bikini top and boy shorts for a more traditional look. The dark blue scoop neck top provides a flattering silhouette while the built-in padded bra offers much-needed support during active pool days. Crafted from a soft polyester and spandex blend, the fabric feels quick-drying and comfortable against the skin.

The tank top is long enough to provide genuine tummy coverage, while the high-waisted boy shorts feature side ties that hug your curves and extend down the thigh for extra modesty. Between the adjustable shoulder straps and the removable padding, you get a customized level of support that makes transitioning from a swim to a family pool party completely seamless.
