Best Bras for Small Busts, According to Fabric Experts and Real Testers
harper wilde, victorias secret, third love

We updated this guide in November 2021 to ensure all products tested and vetted by the Good Housekeeping Institute Textiles Lab were in stock and included updated prices. We added 7 new picks from brands such as Aerie and Lively based on updated testing by Textiles Analyst, Emma Seymour and Textiles Lab Director, Lexie Sachs. We also added highlights about why we love each and anything you should take note of before you buy.


From wireless bras to strapless bras, bralettes and everything in between, finding the perfect bra is difficult enough, but if you have a smaller cup size, it can seem impossible to find the right style of bra for you. Whether you have a petite frame or a small cup size, you need a bra that'll fit well and be supportive without all features in styles designed for larger busts.

While it may be tempting to skip the hassle of a bra altogether, Lori Bergamotto, Good Housekeeping Style Director, advises against it. “​A common misconception about bra shopping for small busts is that support doesn’t matter. Small breasts need support too; it adds volume, maintains shape and can make some clothes look like a better fit as well.”

Since you want to make sure you're spending your money on bras that fit well and are worth the splurge and will last over time, the experts in the Good Housekeeping Institute Textiles Lab put bras to the test to find the ones that are durable, comfortable, supportive and look great under clothing. We evaluated the durability of each bra by measuring its ability to recover from being stretched, as well as shrinkage and signs of wear after five wash cycles. We also had people with a wide range of band and cup sizes wear the bras for a minimum of two days, reporting on aspects like fit, comfort, support, appearance, how well they stayed put and how easy they were to put on and take off. Here are the best bras to buy for small busts:

Best Bra for AA-A Cups
Limitless Wirefree Bra
Pepper
Pepper wearpepper.com
$48.00

It's hard enough to find bras that come in AA and A cup sizes, let alone ones that 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. This style in particular is soft, stretchy, and wireless. It has thin, adjustable straps and a low neckline so it can be worn discreetly under most clothing, plus it has removable cups depending on how much shaping you want. The brand also makes an underwire bra for small busts with lightly lined cups that are specially shaped to avoid gaps in the fit. There's also a layer of mesh around the cups so help with the fit and give a flattering look.

Available in sizes XSXL for band sizes 3240 and cup sizes AAB.

  • Designed for small busts
  • Soft and stretchy
  • Removable cups

  • May show some stitching under a tight shirt

Best Value Bra for Small Busts
Oh So Light Comfort Wire Free Bra
Hanes
Hanes amazon.com
$15.99
$13.84 (13% off)

Don't let the price fool you; despite being one of the least expensive bras in our test, this one was also a top performer. It completely recovered its shape after being stretched out in the Lab and it washed well with hardly any shrinkage or wear. It looks somewhat like a bralette, but it has adjustable straps and a hook-eye closure in the back. The foam cups give a nice shape for smaller cup sizes without having underwires that poke. Our testers said it was comfortable and surprisingly supportive for not having an underwire. They also raved about how lightweight it felt and one even said she forgot she was wearing a bra.

Available in sizes S3X for band sizes 34–50 and cup sizes AD.

  • Top-performer in tests
  • Lightweight
  • Durable

  • Some reviewers say this runs small and may want to size up

Best Push-Up Bra for Small Busts
Wear Everywhere Push-Up Bra
Victoria's Secret
Pink victoriassecret.com
$34.95

Pink's push-up bra is one of the few styles out there that even comes in AA cup sizes, and top of that it's super popular with hundreds of five-star reviews online. Users say it feels comfortable to wear, fits perfectly, and looks amazing under clothes. It's padded to give a rounded shape and has underwire support, plus the adjustable straps can convert to a cross-back for racerback tops. It also comes in lots of colors and prints and the option for lace or smooth fabric.

Available in band sizes 32–36 and cup sizes AADD.

  • Comfortable
  • Fits well
  • Padded

  • May have too much padding for those that prefer a natural look

Best T-Shirt Bra for Small Busts
Perfectly Fit T-Shirt Bra
Calvin Klein
Calvin Klein amazon.com
$30.42

A good T-shirt bra should be discreet even under tight-fitting tops, and this one got a perfect score for looking invisible under clothing. It's a basic, no-frills bra that was especially liked by B-cup testers, who called it "the perfect everyday bra." They raved about its comfort and said it had just the right amount of padding. On top of looking great under clothes, it also ran very true to size and was easy to get on and off. It washed well in Lab tests with barely any shrinkage, plus it comes in a variety of colors.

Available in band sizes 3040 and cup sizes ADDD.

  • Invisible under clothing
  • Runs true to size
  • Washes well

  • Stretched out a bit in lab tests
5
Best Bra for B Cups
The Base
Harper Wilde
Harper Wilde harperwilde.com
$40.00

When we tested this lightly-lined underwire bra, it was especially loved by B-cup testers because it gave great shape without too much padding. Testers rated the bra both supportive and comfortable — one even said it was the softest bras she's ever tried. In the Lab, it washed well without shrinkage or damage. It also has clever features, like straps that adjust in the front (genius!) and a hook that converts it to a racerback. Plus, the online-only brand has free shipping both ways so you can try on multiple bras at home and send back the ones you don't want. And if you're looking for a strapless bra, the brand's strapless version was another favorite for B-cup testers.

Available in band sizes 3242 and cup sizes AF.

  • Gives shape without too much padding
  • Loved by B-cup testers
  • Supportive and comfortable

  • Less suitable for A and AA cups

Best Triangle Bra for Small Busts
The Stripe Mesh Bralette
Lively
Lively wearlively.com
$45.00

Not only is this bra great for small busts but the triangle-shaped cups make it easy to wear under V-cut tops and tanks. It has a wide elastic bottom for added support and the lightly lined cups are removable for a more minimal look.  Good Housekeeping’s Textiles Analyst, Emma Seymour, recommends bralettes because, “they offer a more minimalist design, yet still provide enough support for small busts.” Testers liked how this bra stayed in place and was easy to get on and off. If you’re in between sizes, the brand recommends sizing up and our testers found going up a size gave more coverage.

Available in sizes XS-XL (cup sizes AA-DD)

  • Great shape for wearing under V-cut tops
  • Removable cups
  • Stays in place

  • May want to size up
7
Best Lightly Lined Wireless Bra for Small Busts
Real Sunnie Wireless Lightly Lined Bra
Aerie
Aerie ae.com
$33.71

This Aerie lightly lined wireless bra earned top marks for appearance and support, not to mention the lightly lined molded cups made it a tester favorite. It’s completely invisible underneath tight clothing thanks to the smooth fabric and lack of hook and eye closure in the back, but take note testers did find it somewhat difficult to get on and off since it needs to be pulled over your head.

Available in band sizes 30-40 and cup sizes A-D

  • Top scores for appearance and support
  • Lightly lined molded cups
  • Invisible under tight clothing

  • Somewhat difficult to get on and off

The Flex strapless bra was a favorite among our B-cup testers because it fit well, felt supportive and looked great under clothing. If you have a hard time finding a strapless bra in an A-cup, Harper Wilde also carries The Flex in sizes 32 to 38 A. While they are online only so there’s no trying on in store, they offer free shipping both ways so you can try on multiple sizes at home and return what you don’t want.

It has drop-down cups making it easy to nurse and adjustable straps are conveniently located in the front instead of the back.

Available in sizes XS-L (cup sizes AA-DD)

I already own five colors at this point.” It’s completely seamless and has a snug yet stretchy fit. It has a plunging neckline so you can wear it under the deepest V-cut tops without it being seen or wear it alone as a top, though some reviewers say the lighter colors are a bit see-through.

  • Plunging neckline
  • Comfortable

  • Runs small may want to size up
  • Lighter colors may be slightly see-through

$65.00

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 at home to find the right fit. Our testers with smaller cup sizes liked how this 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. They also commented on how comfortable the fabric was. In the Lab, it held up during the wash cycles and didn't shrink at all.

Available in band sizes 30–48 and cup sizes A–I.

  • Comes in half sizes
  • Comfortable fabric
  • Does not shrink in wash

  • Pricey
12
Best Bralette for Small Busts
Never Say Never Sweetie Bralette
Cosabella
Cosabella amazon.com
$39.31

It may look delicate, but this lace bralette proved to be durable in our tests: It recovered well from being stretched and washed well without shrinkage or signs of wear. Testers loved the look of it, calling it "really cute and stylish" (and as a bonus, it's available in a rainbow of colors). Keep in mind: it's not necessarily for everyday use  several noted it's hard to wear under most clothing due to the lack of support, and some felt that the straps sat too far out. Still, most said it was overall comfortable and it's a good option for those with smaller sizes that prefer a bralette style.

Available in sizes S–XL.

  • Durable
  • Stylish
  • Available in a variety of colors

  • Not for everyday use

Best Seamless Bra for Small Busts
True Body V-Neck Bra
True & Co
TRUE & CO. norsdstrom.com
$49.00

This pullover style is incredibly smooth and lightweight. Size A cup testers especially liked it, saying it felt super comfortable while still being supportive. The fabric also proved to be durable, standing up to stretch recovery and wash tests. One thing to note: Testers didn't love its appearance and said it's hard to wear under certain clothing, but they still called it the perfect bra for lounging because it feels like you have nothing on.

Available in sizes XSXL for band sizes 30–40 and cup sizes AD.

  • Loved by A-cup testers
  • Good for lounging
  • Comfortable

  • Hard to wear under certain clothing
14
Most Innovative Bra for Small Busts
Bra-Llelujah Bralette
Spanx
Spanx amazon.com
$47.98

Spanx's Bra-Llelujah collection uses a smooth hosiery-like material for the straps and back so it feels insanely comfortable and won't dig in. The full coverage bra is a favorite among our larger-cup testers (and it's also available in A and B cups if you prefer more support), but this pullover version is more minimal and has 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 are big fans of the unique material that lays flat and feels great while still offering support.

Available in sizes XSXL for band sizes 30–40 and cup sizes ADD.

  • Unique hosiery-like material
  • Extremely comfortable
  • No underwire

  • Straps are a bit wide

Best Natural Shape Bra for Small Busts
The Scoop
Cuup
Shop Cuup shopcuup.com
$68.00

This unlined style from Cuup is made without padding, making it ideal for anyone that prefers a natural shape without excess material. It also has flat straps that sit comfortably on your shoulder without digging in and a scoop neckline so you can wear it with low-cup tops. It's available in a wide cup-size range, but testers with smaller busts especially liked how comfortable it felt and how it stayed in place all day. It still offers support with its underwire, but users told us it didn't poke or prod them while wearing.

Available in band sizes 30–38 and cup sizes A–H.

  • Straps and underwire do not dig in
  • Stays in place

  • Pricey

Best Front-Close Bra for Small Busts
London X-Back Bra
Giapenta
Giapenta giapenta.com
$68.00

Perfect for anyone that struggles to put on a bra and keep it in place throughout the day, this one's designed with a front closure, front strap adjustments and an X-back to help keep straps from sliding off your shoulders. One of Bergamotto’s favorite behind-the-scenes photoshoot secrets is criss-crossing straps like these: “Criss-crossing straps add shape by drawing all the breast tissue firmly into the cup and creating more volume.” It has a low cut in front, and those with smaller cup sizes told us it held everything in well. In Lab tests, there was no shrinkage or signs of wear after washing and it recovered well from being stretched out. Most testers found it to be comfortable, though some did say the underwire dug in a bit. Still, they gave it good scores for support and said it looked great under clothing.

Available in band sizes 3238 and cup sizes ADD.

  • Front closure
  • X-back to help keep straps from sliding off
  • Washes well

  • A few testers said wire dug in a bit

It's Amazon's best-selling adhesive bra with thousands of five-star reviews and is designed to look and feel seamless under clothes.

It's versatile to wear for everything from gym workouts to running and has a racerback design for a good range of motion.

$48.00

Not only does AnaOno offer bras for small busts but they specialize in offering bras related to breast cancer treatments, such as pocketed mastectomy bras, reconstruction bras and radiation therapy bras as well as post-surgery loungewear. We especially love the Maggie bralette for its beautifully stretchy lace and pockets for optional breast forms (not included) or bra pad inserts. When we road-tested this bra at home, the wide elastic band was soft and comfortable while still offering support, though we did have to size up.

Best Bra Tank for Small Busts
The Everyday Tank With Built-in Bra
Free Reign
Free Reign freereignstyle.com
$74.00

Finding a tank with a comfortable built-in bra can be challenging but this one from Free Reign does it right. It’s specifically made for those with smaller busts and comes in sizes 32A to 36B. When we tested this at home, we loved the soft material and especially the built-in bra. Unlike most built-in bras, the band wasn’t too tight and made with a smooth elastic material. The cups are sewn in so there’s no fussing with bra inserts. The one drawback, it only comes in black and white.

Available in size 32A-36B

  • Built-in bra
  • Comfortable material
  • Sewn-in cups

  • Only available in black and white
