20 Best Bras for Small Boobs That Are Light and Comfortable

Finding the best bras for small boobs isn’t always as simple as grabbing the smallest size on the rack. As anyone who wears an A- and B-cup knows, many styles are designed with large busts in mind—but on a flatter chest, they can awkwardly gape or rely too heavily on stiff padding and underwire to create shape that doesn’t look or feel natural. Much like shopping for bikini tops for small breasts, success often comes down to closer-fitting cups, thoughtfully-placed foam, and adjustable straps that work with your proportions rather than against them. Fortunately, plenty of lingerie brands cater specifically to petite busts, whether you’re after a comfortable bralette, a strapless bra that stays in place, or a push-up style that adds seamless structure and volume. Below, we’ve rounded up our favorites, all tested and recommended by Glamour editors.

Best push-up bras for small busts

Push-up bras are a classic choice for small chests, especially if you’re looking to create noticeable shape under a fitted top, special-occasion dress, or low-cut neckline. The best ones aren’t overly stuffed; instead, they lift breast tissue upward and inward for a more natural-looking boost. Pepper is perhaps the best-known bra brand for small boobs, and its Lift Up Bra is one of our top picks for AA to B cups. Its lightweight cups sit flush against the chest without gapping, and gradual padding and light underwire create a natural shape without looking overdone. (It comes as a bikini top, too.) If maximum enhancement is the goal, Victoria’s Secret’s Bombshell bra adds up to two cup sizes of volume.

Best bralettes for small busts

Bralettes are another popular choice for small busts, since they provide light, usually wireless support without the padding and heavy structure built into most traditional bras. They’re easy to wear all day (and even to sleep) and less prone to the cup gaping that can occur with molded styles. Triangle bralettes work especially well on smaller chests because their plunging neckline highlights the cleavage, while racerback styles create a closer, more secure fit. We love True & Co.’s hard-working, wire-free triangle bra, which has silky-soft molded cups with convertible straps that switch it into a racerback.

Best T-shirt bras for small busts

Few undergarments get more everyday wear than T-shirt bras, which are defined by smooth cups that stay invisible under thin knits, fitted tops, and dresses—ideally with no gaping. Natori’s Feathers bra has earned a devoted following among lingerie experts and editors for its shallow plunge cups, which fit snugly against flatter chests. Another great pick is ThirdLove’s 24/7 Classic, which comes in half bra sizes for a uniquely customizable fit and offers smooth shaping without bulk.

Best strapless bras for small busts

The challenge of choosing a strapless bra for smaller busts is that it has to fit really, really closely to the chest—or it leaves noticeable gaps at the top of the cups. Not to mention that you may also need a shorter band size. While nipple covers and sticky bras are a smart solution for many low-cut or backless dresses and tops, sometimes you want a true strapless bra for its coverage, security, and shaping. The bras ahead are designed with that in mind, offering a close fit, supportive underwire, and versatile straps that can be worn multiple ways.
