17 Best Bras for Small Busts, Tested by Experts

Dubbed "life-changing" by our testers with AA and A cup sizes, Pepper's bras not only come in small sizes, but they actually fit. Pepper only designs bras for small busts, so you know it's not just a scaled-down version of a larger-sized bra. The Classic All You bra is the brand's best-selling style, featuring shallow cups that are lightly lined for a nice shape without bulky padding. The mesh detailing is not attached at the top of the cups, eliminating extra stitching for a smoother look under clothes.

When wearing Pepper bras, testers were impressed with the fit. One tester who wears an A cup shared, "Most bras I wear always leave empty gaps in between the cups while the band fits, but with this bra, my boobs were covered and supported." This bra kept its shape during our stretch recovery tests in our Lab, but some testers noted that the straps weren't as supportive after extensive use.

When we tested this lightly-lined underwire bra, it was especially loved by B-cup testers because it gave a nice shape without too much padding. Testers rated the bra as both supportive and comfortable, and one even said it was the softest bra she'd ever tried. Another shared, "It was silky smooth and very comfortable to wear even in hot weather." A B-cup tester reported, "This bra was very supportive in all the right ways. It did so without putting strain on my back as well."

In our Textiles Lab tests, it washed well without notable shrinkage or damage. It's also equipped with clever features like straps that adjust in the front (genius!), a crossover front gore for a better fit and a hook that converts the bra to a racerback. Some testers had to try a few sizes to find their best fit, but this brand offers free returns so it's easy to try a variety of sizes to find your perfect bra.

Don't let the price fool you; despite being one of the least expensive bras in our test, it was a top performer. It completely recovered its shape after being stretched out in the Lab, and it washed well with hardly any shrinkage or visible wear. While it looks more like a bralette, it has adjustable, convertible straps and a hook-eye closure in the back like a standard bra. The foam cups give a nice shape for smaller cup sizes, and there are no underwires that poke and prod. We love the mesh details for a breathable, comfortable feel.

Our testers said it was comfortable and surprisingly supportive for not having an underwire. They also were impressed by how lightweight it felt, and one even said she forgot she was wearing a bra. This bra is sold in S/M/L sizing, so it can be harder to find the right fit for people who have a smaller cup size and a larger band size.

The silky soft feel of this Everlane bra sets it apart from other bras we've tested. "This bra is so smooth and lightweight," reported one satisfied tester who added, "The silky, smooth fabric feels amazing on your skin. It's buttery soft, so I completely forget I am wearing it." The plunge cut and triangle cups offer great support for smaller bust sizes (though likely not enough coverage for larger busts).

We love the longline design and that the straps are wide for support but can still be adjusted. Because the bra pulls over your head with no back clasps, some testers found that they got deodorant on the bra more often, but overall, the bra was well-received and earned top marks for comfort, support and fit. Multiple testers declared it their "new favorite bra."

This Pepper bra offers support and coverage without a stiff underwire. It's made with soft and stretchy material that our testers described as "silk-like" and features adjustable straps with a hook-eye closure for a more secure feel. One A-cup tested said this bra was "extremely comfortable to the point of not feeling it," and a B-cup tester said she "highly recommends this bra."

While it's available in sizes XXS to XL, it's not standard sizing. The bra is specifically designed to fit smaller cup sizes, accommodating traditional bra sizes 30A through 40A, so if you have a larger band measurement, you won't have to worry about too-big cups. We found that the bra can be worn discreetly under most clothing, thanks to the scoop neckline, though some testers pointed out that the stitching on the bra was visible through more fitted tops.

If you're hoping to boost your cleavage, a properly fitted bra that supports your natural shape is key, but adding some extra push-up padding can really enhance your chest. This Victoria's Secret Pink push-up bra is one of the few push-up styles we've evaluated that's available in AA cup sizes, and it's designed with padded cups that add up to one additional cup size of fullness for a super lifted look. In addition to the padding, the bra straps are adjustable and can be converted to a cross-back style for even more lift.

GH analysts who have worn this style say the underwire bra is supportive yet comfortable, and they especially love the smooth material option, describing it as "silky and soft." Our testers who have worn other bras from VS Pink share that the bras stay in place without riding up but have noted that they've had to size up because the brand's bras run small. In Textiles Lab tests, VS Pink bras recovered to their original shape after being stretched, and they performed well in the wash with only minor shrinkage.

A good T-shirt bra should be discreet, even under tight-fitting tops, and this one got a perfect score in our Lab tests for looking invisible under clothing. It's a basic, no-frills bra that our B-cup testers especially liked, calling it "the perfect everyday bra." They gave high marks for comfort and said it had just the right amount of padding. On top of looking amazing under clothes, it also ran very true to size and testers said it was easy to get on and off. It washed well in our Lab tests with barely any shrinkage (although it did stretch out a bit), plus it comes in a variety of colors.

Perfect for daily wear, a nude bra is easy to hide under all kinds of clothing for a seamless look, but it can be difficult to find the perfect nude that actually matches your skin tone, especially since most bra brands only offer one or two "nude" shades. Skims offers a whopping nine nudes to choose from to suit a variety of skin tones.

Our testers appreciated that the bra accommodates those with larger band sizes and smaller cups, with A-cup options available in up to a 44 band. The t-shirt-style bra has molded demi cups and minimal padding for a natural look that lies flat against the chest without gaping. Testers loved the soft material and shared that it didn't cling to their shirts, but some testers felt like the underwire extended too far backward into their armpits, causing it to dig in.

This Aerie lightly lined wireless bra earned top marks from our testers for appearance and support, and the lightly lined molded cups made it a favorite. It’s invisible underneath tight clothing, thanks to the smooth fabric and lack of hook-eye closure in the back. Some testers did find it somewhat difficult to get on and off since it needs to be pulled over the head, emphasizing that the band felt too tight and recommending that others size up.

If a wireless lightly lined bra isn't for you, there are tons of other variations, including push-up, strappy and full coverage styles. One Textiles Lab analyst only wears Aerie's Sunnie bras and says every style she has tried is comfortable. Our testers who tried other styles from the Aerie Sunnie collection made of the same material rated them highly for overall comfort, with one tester sharing, "The cups and band feel buttery soft on my skin."

Spanx's Bra-Llelujah collection uses a smooth hosiery-like material for the straps and back that feels super comfortable and won't dig in. Plus, it provides the smoothing effect that Spanx is known for, with the thicker band shaping the underarms and back, preventing unwanted bulging.

The brand's full-coverage bra is a favorite among our larger-cup testers (and it's also available in A and B cups if you're looking for a bra with more support), but this pullover version is more minimal with no underwire. Just note that the straps are a bit wide, and they didn't keep their shape quite as well as other styles in our stretch recovery tests. Still, we appreciate the unique material that lies flat and feels comfy while offering support.

The Little Bra Company specializes in bras for petite frames, and the Sascha bra is a good pick for smaller cup sizes. It's convertible, which means it can be adjusted to be worn in strapless, standard, racerback, one-shoulder and halter styles.

Testers were impressed by the small inner pocket that allows you to easily adjust the level of padding in the bra — just pull the padded fill out for less lift. Most lace materials are textured and visible under clothing, but we love that this bra is designed with flat lace, so it should look great under tops. Online reviewers and the brand say the band runs tight, so keep that in mind when choosing your size — you might want to size up.

With adjustable straps, a breathable mesh band and hook-eye back closure, this bra from Parade may seem like a regular bra, but it doesn't have a stiff underwire or thick padding. Most importantly, according to users, it's super comfortable. We love that it's made from recycled nylon that has a smooth and silky feel. The deep-V neckline makes it easy to wear under lower-cut tops, and you can choose from nearly 20 colors to coordinate with your favorite underwear.

One A-cup user shared that she was shocked by how supportive the bra felt, explaining, "It almost reminds me of how a sports bra fits: It hugs you and makes you feel like you won't bounce." While we haven't tested or washed this style in the Textiles Lab, users who have washed it say that it doesn't pill or look misshapen after laundering. Parade uses a unique sizing system, so we recommend checking out the size guide before buying because some online reviewers struggled to find their perfect fit.

If you constantly feel like you can't find the right size, ThirdLove has unique half-cup sizes, like "A 1/2" for those between A and B. The brand recommends taking a quick quiz to find your best style and size, but this T-shirt bra is its bestseller. It's pricey, but the site offers free return shipping so you can try on multiple sizes at home to find the right fit.

The bra received near-perfect scores across the board in our consumer test with top marks for fit, comfort, support and appearance. Our testers with smaller cup sizes liked how this style offered a nice shape without too much padding. One A-cup tester said she typically purchases push-up bras for some lift but didn't feel that she needed the extra lift with this one because of its supportive shape. She also commented on how comfortable the fabric was. In the Lab, it held up during our wash cycles and didn't shrink at all, but some consumer testers said it looked a little misshapen after laundering.

Bras with wider band sizes and small cups are difficult to come by, but Lulalu has you covered — the t-shirt bra is available in cup sizes AAA to A and band sizes 30 to 42, and there's even a quiz to help you find your perfect fit. We appreciate the removable inserts, so you can adjust the level of padding, and we love that the foam cups are molded to maintain their shape.

Although we haven't tried this pick out in our Textiles Lab yet, we like that it's made with a cotton and lycra blend fabric, which should feel lightweight and comfortable. Online reviewers say the bra is "smooth and flattering," and they're grateful to have found a brand with bras that actually fit alongside the small cups, but there are some reviewers who say the band runs tight.

Designed without padding or lining, this mesh bra from Cuup is ideal for anyone who prefers a natural shape without excess material or bulk. You're able to wear the bra under lower-cut tops and dresses thanks to the scoop neckline, and the flat straps with chic gold hardware sit comfortably on your shoulders without digging in. We love that it's available in dozens of colors, including everyday neutrals and fun bright hues like teal, mint and orange.

The bra is offered in a wide range of cup and band sizes, but our testers with smaller busts especially loved the bra, sharing that it felt comfortable to wear and stayed in place all day long. Though there's no lining or padding, the bra is still equipped with an underwire that lies flat against the chest, and our testers say it didn't poke or prod. Some testers felt like the band was a bit tight, so you may want to consider sizing up for a more comfortable fit.

Perfect for anyone who struggles to put on a bra, this one's designed with an easy-to-use front closure and front strap adjustment, so you don't have to reach around your back, and you can easily slide the straps to achieve the perfect fit. An X-shaped back keeps the straps in place so they don't slide off your shoulders.

Our testers with smaller cup sizes say that despite the shallower cup design, the bra held everything in well without bulging or slippage. Most testers rated the bra highly for comfort, but a few testers said the underwire dug in a bit. Still, they gave the bra good scores for support and noted that it looks great under clothing. In our Textiles Lab washability tests, there was no notable shrinkage and no signs of wear post-wash.

Cosabella's bralettes are a favorite of our testers who say the lace designs are "comfortable and sexy at the same time." This all-lace style stood out for its support even with no lining or underwire. The straps can be also adjusted for additional support and lift. One tester said, "I couldn't believe the amount of lift I was getting without underwire. I'm really, really impressed," and another added, "I have never in my life worn a bralette as supportive as this."

Some testers shared that the band rolled up throughout the day, but they gave the bra high scores for comfort overall. Testers who normally avoid lace bras because they're itchy and uncomfy were blown away by how soft the lace felt. We love that there are more than 30 colors to choose from. For those with a smaller band size and small cups, the brand carries a petite option, as well as a larger option for those with larger band sizes and small cups. Plus, you can match this pick with Cosabella's underwear for a complete coordinating look.
