Best Bikini Tops for Small Chests: Find Brands That Both Fit and Flatter

When summer rolls around, some swimsuit lovers don’t always get the chance to wear the bikini they love, considering not all items are made to fit all sizes. Those with smaller chests can attest to the tedious process of finding a bikini top that fits with proper coverage. What’s more, even if the bikini fits, there’s no guarantee that the garment will be fashion-forward enough for their liking.

Fortunately, it doesn’t have to remain this way forever, as there are swimwear brands out there specifically tailored for smaller chests. And the best part is that these companies ensure they’re not lacking in other areas such as style, sustainability and longevity.

Shop our favorite bikini brands for small chests

Bikinis should make everyone feel sultry and confident, no matter their chest size! Below, check out a few of our favorite brands that keep smaller chests in mind when it comes to their bikini top designs.

Lou Swim

Lou Swim is the perfect place to start our list, as the brand stands firm in its commitment to creating sustainable styles for smaller chest sizes. “Designed to flatter and empower smaller chests” is their mantra. The brand promises there will be little to no gaps in their top while also providing a natural lift and comfortable wear that lasts.

Their Ellie Top ($78) features a flattering ruched design and is available in six eye-popping colorways, while their Erin Top ($78) provides a unique shape without sacrificing coverage.

Pepper

Founded by women tired of the fashion industry pushing smaller chests out of the beauty standard, Pepper aims to put these sizes back in the narrative. “I know what it’s like to wear a bikini and not fill it in, and feel completely self-conscious about it in public,” Pepper co-founder Jaclyn Fu previously shared with SI Swimsuit. “For too long, it felt like we had to choose between swim tops that fit around the band but not the cups, shopping in the teens’ department as an adult or settling for boring styles. You want to feel confident in a swimsuit.”

The Plunge Bikini Top ($68) includes the brand’s “Lift Up padding,” which is designed to “fit snug for maximum lift.” On the other hand, the Triangle Bikini Top ($60) is a can’t-go-wrong classic with its timeless shape, and the top even comes with “removable cups” so you can alter the fit to your liking.

Aerie

Aerie has always been a go-to place for beautiful, affordable undergarments, and the brand is just as talented in its swim department! With pieces ideal for smaller sizes, these beachwear ensembles offer high-quality styles that don’t ignore the fit. And if customers want a different look or feel, they always have options! Aerie offers pieces with removable pads, mix-and-match styles and more.

Try the Aerie Pique Bandeau Bikini Top ($44.95) for a unique look with a sweet mermaidcore vibe, or for added lift and shape, snag the Aerie Pique Unlined Underwire Bikini Top ($44.95).

Knix

Whether a solid bikini is preferred for the summer or you’re loving patterns, Knix is a great one-stop shop for tops in a vast range of colors, designs and, most importantly, sizes. This brand is also a stellar option for those who could use a little more sun protection. Creating bikinis out of premium UPF 50+ fabric, Knix makes it easy for beachgoers to get that triangle cup-shaped bikini tan without putting their skin at major risk.

If you’re looking to add a few pieces to your cart, the Sculpt Front Tie Bikini Top ($65) offers excellent comfort thanks to its “wireless support.” Alternatively, if you’re looking for something a little different, the Cap-Sleeve Bikini Top ($65) is a fun, athletic option.

Sabal Swim

Sabal Swim goes the distance with its high-quality, affordable products, while never sacrificing the ideal fit. These tradition-breakers set their own pace, delivering “small but mighty” bikini tops that might be hard to find elsewhere. And, if there is any need to return a product for a better fit, the brand works with customers by offering easy-to-follow size guides and return/exchange processes.

The Cleavage-Enhancing Seaside Bikini Top ($118) is a best-seller for a reason, boasting the brand’s “proprietary CupUp™ booster technology” that adds “up to 2 cup sizes.” Or if you’re hoping to rock a more traditional-looking style that still offers plenty of push, try the Sculpting Hampton Triangle Halter Top ($95).

SAME Los Angeles

SAME Los Angeles is absolutely worth the splurge! For bikini tops that emphasize smaller chests, the price is proportionate to the satisfaction. Because the brand runs small, they mean it when it says an XS is an extra small. Yes, even swimwear lovers with smaller chests can rock micro bikinis effectively!

Make a statement like our models did at the SI Swimsuit Runway Show in Miami by channeling your inner “Biker Babe” with the Fringe Triangle Top ($158) or shimmer on the shoreline in the dazzling Hammer Pearl Top ($158) featuring “custom hammered hardware.”
