Triangle bikini tops are practically synonymous with swimwear for small boobs; their minimal coverage, adjustable straps, and barely-there shape naturally highlight the chest instead of overwhelming it with bulky padding. “The less fabric, the better for enhancing the curves,” says Red Carter, designer of the eponymous swim label. Another perk: Since most triangle tops tie at the neck and back, they’re especially easy to customize for a closer, more cleavage-boosting fit without gapping. The swimsuit styles below range from supportive to skimpy string bikini tops, including Pepper’s triangle top designed for AA to B cups (the brand is known for its bras for small boobs), Skims’s viral bandana-print bikini, and a $25 top from Quince in a vivid pink.

Push-up bikini tops sometimes get a bad rap for looking overly stuffed, but they do the most when it comes to creating shape, lift, and cleavage if that’s the effect you’re after. Many newer designs rely on strategic ruching, molded cups, or tapered padding rather than stiff foam inserts that feel bulky and dig in. Pepper’s Lift Up bikini top, for instance, has lightly lined cups that gradually build volume for a natural-looking boost, along with adjustable straps and a customizable back fit. Victoria’s Secret’s on-trend eyelet style offers up to an extra cup size of oomph, while still allowing for flexibility with removable padding, as does the budget-friendly Cupshe option below.

Halter bikini tops (and one-piece swimsuits) are one of the best swim styles for smaller breasts because their adjustable neck ties cinch the fit in front, reducing the gapping that often occurs with more structured tops. One of our favorite styles is Left on Friday’s Reef Top, which is designed for A to C cups and can be styled multiple ways—including crossed in the front or back or draped over one shoulder. The cutout detail draws the eye toward the center of the chest, creating the look of more cleavage. Spanx’s halter style, meanwhile, features soft, wide straps that can be tied as snugly as you like for a more secure, sculpted fit.

Underwire bikini tops create definition and shape for small breasts without necessarily relying on heavy padding. “Look for a top with soft cups that will conform to your body—they’ll actually give you a little boost,” says Jude Al-Khalil, founder of swimwear brand Bikyni. TA3 (which makes some of our favorite bathing suits for large busts) tops feature comfortable adjustable straps and removable push-up padding, while Boden’s bra-sized swim tops make it easier to find a precise fit. Monday Swimwear’s underwire top, meanwhile, come in an inclusive range of fits—from Petite Petite to Very Voluptuous—and features a subtle “V” taban at the center of the bust that draws the eye toward your cleavage.

Small chests tend to wear bandeau bikini tops especially well, since they require less support to stay comfortably in place than they often do for larger busts. Most styles are minimally structured and unpadded, creating a sleek, usually strapless silhouette—not to mention fewer tan lines. Left on Friday’s sporty tube top has lightly compressive fabric that keep it from sliding around, and this Zaful bikini lets you adjust its fit with a tie-back.
