The 15 Best Bras for Small Busts That Don’t Skimp on Comfort

In the past, fashionable, comfortable bras for small busts were like unicorns in the lingerie section—impossible to find. Speaking from personal experience, bras tend to be either overly feminine or too simple for small busts.

The fit test would be compromised if a bra passed the style test. I was left with slipping straps, gaping cups, and way too much padding in bras designed for petite busts that appeared wearable.


That was then. With the finest bras for tiny busts, I can now put old complaints to rest and receive fresh comments. By 2022, there will be just as many 32AA-focused brands as 36B- and C-focused ones. No longer are push-up bras or full-coverage triangle bras the only options for women with petite busts. Shallow cups, adjustable straps, and—finally—removable padding are all design elements specifically suited for petite breasts in new forms.

Some petite bust styles from ThirdLove and Cuup are so lovely that they nearly beg to be worn alone. Then there are companies like Pepper that solely make bras for petite boobs.

Here, we’ve outlined the top bras for tiny busts based on fit and purpose. These 20 bras for small busts have you covered whether you’re looking for a no-slip strapless bra, a convertible nursing bra, or an everyday t-shirt bra.

1. PEPPER – Limitless Wirefree Scoop Bra

Finding bras that really fit is difficult enough, let alone those that are available in AA cup sizes. Since Pepper only creates bras for women with small busts, you can be sure that it is not merely a smaller replica of a larger-sized bra. Particularly soft, elastic, and wireless describe this style. It may be worn covertly under most garments because of its thin, adjustable straps, low neckline, and removable cups, which you can remove according to how much shaping you desire.

The company also produces an underwire bra with lightly lined cups that are precisely contoured to prevent fit gaps for women with petite busts. Additionally, there is a layer of mesh around the cups to improve fit and provide a feminine appearance.

2. HARPER WILDE – The Base

B-cup testers particularly favored this lightly lined underwire bra throughout our testing since it provided a beautiful shape without providing too much padding. The bra received positive reviews from testers for its comfort and support; one even called it the softest bra she had ever worn.

It washed well in the lab without shrinking or suffering any damage. Additionally, it has ingenious details like front-adjustable straps (brilliant) and a hook that makes it into a racerback. Additionally, the online-only retailer offers free returns, allowing you to try on many bras at home and return the ones you don’t like.

3. HANES – Oh So Light Comfort Wire Free Bra

Don’t be deceived by the price; although being one of the most affordable bras in our test, this one also delivered excellent results. After being stretched out in the lab, it totally regained its shape, and it washed well with virtually any shrinkage or wear. Although it features adjustable straps and a hook-eye closure in the back, it partly resembles a bralette.

For smaller cup sizes, the foam cups provide a lovely form without any protruding underwires. Despite not having an underwire, it was surprisingly supportive and comfy, according to our testers. Additionally, they gushed about how light it felt; one even claimed to have forgotten she was wearing a bra.

4. SEAMLESS UNIVERSAL – Plunge Bralette

Designed with a silky polyester outside fabric but coated with a cotton fiber for a more comfortable feel, lab professionals adore this pullover style bra from Parade. Analysts are delighted by the seamless construction, which ensures that no wires or stitching will show through your clothing. The plunging neckline and back are ideal for low-cut tops.

Despite being without wires or cups, reviewers claim that the bra is supportive and lifts. Be sure to check the sizing chart for your best fit as some reviewers did report gaps along the bra’s sides while others noted that it runs on the smaller side.

5. PINK – Wear Everywhere Push-Up Bra

The push-up bra from Pink is one of the few designs out there that comes in AA cup sizes, and on top of that, it’s incredibly popular with hundreds of five-star ratings online. Users claim that it is cozy to wear, fits perfectly, and looks stunning beneath clothing.

We are impressed by the adjustable straps that can be quickly changed into a cross-back for racerback tops. The bra is cushioned to give it a rounded shape and features underwire support.

Additionally, it has a front closure option, which we found to be easier to put on, particularly if you have limited movement, and it is available in a variety of colors and prints.


The Sascha bra from The Little Bra Company, which specializes in bras for small-framed women, is a fantastic option for lower cup sizes. It can be modified to be worn in strapless, regular, racerback, one-shoulder, and halter styles because it is convertible.

The small inner pocket that makes it simple to change the bra’s level of padding is praised by our Lab experts. Simply pull the cushioned fill out for less lift.

We appreciate that this bra is made with flat lace, as opposed to most lace fabrics, which are textured and easily apparent under clothing. Consider this while selecting your size because reviews and the brand both claim that the band runs small.

7. CALVIN KLEIN – Perfectly Fit T-Shirt Bra

This T-shirt bra received a flawless score in lab testing for seeming invisible beneath clothing. A decent T-shirt bra should be discrete, even under tight-fitting garments. Our B-cup testers thought it was “the perfect everyday bra” because it is a simple, no-frills bra.

They gushed about how comfortable it was and how the padding was exactly right. In addition to fitting well and looking wonderful beneath clothing, it was very simple to put on and take off. It comes in a range of colors and is washed nicely in lab testing with scarcely any shrinkage.

8. LIVELY – The Mesh Trim Bralette

This bra is suitable for tiny busts and is also simple to wear under V-cut blouses and tanks due to the triangle-shaped cups. The lightly lined cups are removable for a more understated appearance, and the bottom has a broad elastic band for increased support.

One analyst remarked that she adores the “chic” mesh panels that line the cups of Lively’s bralettes, which are a favorite among experts. This bra was easy to put on and take off, and testers loved how well it held its shape. The brand advises sizing up if you’re in-between sizes, and our testers discovered that doing so provided extra coverage.

9. HARPER WILDE – The Strapless

A lot of our testers with petite busts prefer Harper Wilde’s bras. Our B-cup testers adored the Strapless bra because it was comfortable to wear, supportive, and fashionable when worn under clothes. We appreciate that it has front-adjustable, detachable straps and an “X” shaped bridge between the cups for a better fit.

Despite the fact that you can only try on the bras online, there is no option for in-store fittings; however, the company does provide free returns, allowing you to try on a variety of sizes at home and return anything you don’t like.

10. AERIE – Sunnie Wireless Lightly Lined Bra

The lightly lined molded cups on this Aerie wireless bra made it a tester favorite. It received high scores for appearance and support. Because of the smooth fabric and lack of a hook and eye fastening in the back, it is virtually undetectable beneath tight clothing.

However, be aware that since it must be dragged over your head, it can be challenging to put on and take off. There are a ton of additional options, such as push-up, strappy, and full coverage styles, if a wireless lightly lined bra is not for you. One Textiles Lab analyst claims that she only uses Sunnie bras from Aerie and that each type is buttery soft and pleasant.

11. LULALU – Delilah Wireless T-Shirt Bra

The t-shirt bra is available in cup sizes AAA to A and band sizes 30 to 42, and there is even a quiz to help you find your perfect fit. Bras with larger band sizes and small cups are hard to find. However, Lulalu has you covered. We value the replaceable inserts since they let you change the level of padding, and we adore the foam cups because they are molded to keep their shape.

Our specialists are impressed by the cotton and lycra blend fabric, which should feel light and comfortable, even if we haven’t tested this choice in the lab. The bra is described as “smooth and flattering” by reviewers, who are happy to have discovered a company that makes bras that truly fit their small cups.

12. THIRDLOVE – 24/7 Classic T-Shirt Bra

ThirdLove offers special half-cup sizes, such as “A 1/2” for those between A and B, if you frequently feel like you can’t find the proper fit. Although the company advises taking a brief survey to determine your ideal design and size, this T-shirt bra is still its top seller.

Although it’s expensive, the website offers free return shipping so you may test out a variety of options at home to get the perfect fit. Smaller cup size testers like how this provided a beautiful form without adding too much padding.

One A-cup tester claimed that even though she usually buys push-up bras for some lift, she didn’t feel the need for it with this one. They also mentioned how cozy the cloth felt. It did not shrink at all during the wash cycles in the lab.

13. LIVELY – The Mesh Trim Maternity Bralette

Lively’s maternity bralette is a great option for a minimal nursing bra if you have a tiny chest, are nursing, and feel like you don’t need much padding and support. It includes a wire-free wide band that aids in keeping it in place and secure. The nylon and spandex blend fabric also makes it lightweight and comfy. Its drop-down cups make it simple for mothers to nurse, and the adjustable straps are conveniently placed in the front rather than the rear.

14. OUT FROM UNDER – Hailey Seamless Plunge Bra Top

Emma Seymour, a Senior Analyst in the Textiles Lab, owns this bra top and swears by it, saying, “I live in this! I already own five colors.” It fits tightly but stretchily and is entirely seamless. The plunging neckline, which makes it simple to wear beneath the deepest V-cut shirts without it being noticed, is appreciated by our Lab professionals.

Additionally, it’s fashionable enough to be worn as a top on its own, however, it’s crucial to note that some reviews claim the lighter colors are a little see-through.

15. COSABELLA – Never Say Never Petite Plunge Bralette

Our testers love Cosabella’s bralettes and think the lace patterns are “very attractive and trendy.” The bralette is made without a hook and eye closure for a more comfortable feel, and although we haven’t tried this particular type, we appreciate that it still has adjustable straps so you can easily shorten or lengthen them for the right fit. Reviewers gush about how comfy it is and how silky the lace material is.

Additionally, there are many vibrant colors to pick from and you may match your bralette to any kind of underwear from the company. To determine the proper size for you, consult the size chart as their sizing varies from that of other brands.
