17 Large Bust-Friendly Swimsuits Lift, Smooth and Stay Put

1. Our Favorite: The knotted shoulder straps on this striped bikini set adjust to your shape, and the high-waisted bottom skims past the midsection. The blue and white stripes feel classic without trying too hard.

2. Rich-Looking: The gold U-wire on this ribbed bikini set adds shaping under the bust without an actual underwire dig. The ribbed texture and a deep V-neckline keep it looking pricier than $34.

3. Sculpting Sensation: The built-in sarong wrap on this one-piece swimsuit adds a layer of compression across the middle while looking like a separate skirt. The tummy-control lining does the smoothing work underneath.

4. Flattering Find: Slip into this blue striped one-piece for a pool day, and the contrasting top and solid bottom create a subtle hourglass effect. The cutout adds interest without showing skin you don’t want shown.

5. Designer-Looking: Gold hardware details on this swim dress elevate the whole look past its $40 price tag. The tummy-control lining smooths through the midsection without feeling like shapewear.

6. High-Waisted Hero: The crossover top on this striped two-piece crisscrosses at the bust for actual lift, and the ruched high-waisted bottom skims rather than clings. The ruching hides what the waistband lines reveal.

7. Coverage Champion: The front-cross design on this V-neck one-piece gives genuine bust support, and the striped top contrasts with a solid bottom for a slimming effect. The tummy control runs through the torso.

8. Ravishing Ruffles: The ruffle halter on this tankini set adds visual volume up top while the high-waisted leopard bottom does the smoothing. The halter straps tie behind the neck for adjustable support.

9. Sporty Support: The supportive top on this color-block bikini has the structure of a sports bra without looking like one. The high-waisted bottoms in contrasting colors stay put through actual swimming.

10. Stay-Put Style: The twist-front detail on this two-tone bikini adds shaping at the bust, and spaghetti straps adjust for the right fit. The high-waisted bottom holds its position when you stand up.

11. Plus Size Perfection: Pack this plus-size bikini for vacation and skip the worry about straps slipping or fabric stretching out. The ribbed texture keeps its shape swim after swim.

12. Seriously Slimming: Slip into this color-block set for a pool party and the contrasting panels do the contouring for you. There’s no suck-it-in required.

13. Poolside Pretty: Wear this V-neck one-piece for a pool day with friends where you want to feel pretty, not just covered. The ruffle adds the prettiness, and the tummy control adds the confidence.

14. Full-Coverage: Bring this floral tankini on a family vacation where you’ll be chasing kids or grandkids around the pool. Nothing shifts, nothing rides up, nothing requires constant adjusting.

15. Support Superstar: The wrap-tie front on this V-neck swimdress adjusts to fit your bust, not a standard cup size. Plus, a side cutout and tummy-control lining round out the support.

16. Poolside Hero: Slip on this V-neck swimsuit for any pool day where you want simple and reliable. No fussing with ties, no adjusting straps, just a suit that works.

17. Confidence Booster: The cross-front V-neck on this high-waisted bikini adds lift and a flattering neckline. The side-tie bottoms adjust to your actual hip measurement instead of a standard size.
