Left on Friday Hi Dive Top and Hi Hi Bottom ($85 each)
The women who designed this wave-ready swimwear wanted it to offer the same support as their favorite workout clothes. The top’s high neck and crossback keeps chests up to a D cup secure, while the high waist and snug-fitting bottom prevent slippage during beach volleyball.
Prana Aquilia Top and Millan Bottom ($70 and $60)
If you want extra protection from the elements, this simple rash-guard set is your jam. The fabric is UPF 50, and the high neck, long sleeves, and cropped torso prevent chafing during long sessions in the water. The Millan bottom provides plenty of coverage.
Title Nine Better Bikini 2.0 Top and Holy Grail Bikini 2.0 Bottom ($59 and $49)
When you have big boobs, bikini tops tend to look matronly or too revealing. Not this suit, which our DD tester found supportive without shading into utilitarian. It’s secure enough for a beach jog yet cute enough for laying out at a pool party.
Andie Tulum One-Piece ($95)
Simple and quick-drying, this mesh one-piece offers ample coverage in front and a low-cut, strappy party in back. It’s functional enough for laps and still looks elegant. The New York City brand has one of the most inclusive size ranges on the market, from XS to XXXL.
Carve Designs La Jolla Tankini and Makaha Skirt ($78 and $58)
This tank-top and skirt combo offers great coverage without getting in the way of water activities. The La Jolla comes in standard sizing and D-DD for those who need more support. The Makaha skirt has built-in briefs with wedgie-proof no-slip seams.
Summersalt High Dive Top and High Leg Mid Rise Bottom ($50 and $45)
A contoured waist, just enough coverage, and sizes from 2 to 22 might just make the High Leg the world’s first universally flattering bikini bottom, especially on women with hips. Pair it with the cutout High Dive top for a flirty and functional set.
