I’ve worn roughly the same bra size since I was fourteen, so I have the equivalent of an advanced degree in small boob life. Years spent searching for the perfect bra taught me a lot about the different breast shapes out there and the right kind of bra for each. (News alert: “normal boobs” are a lie.) Just like with bra shopping, the best bikinis for small boobs are the ones that fit your natural shape, whatever that happens to be. Most importantly, it should be a style you freaking love, regardless of what the experts say is “best" for your chest.
To find swimwear that married style and function, I consulted breast shape dictionaries and spent an inconceivable amount of time on Reddit’s r/ABraThatFits to scout out which bikinis would be good for particular breast shapes. For example: widely spaced breasts might prefer an adjustable triangle top or a lace-front style, while athletic or shallow breasts (that sometimes deal with gaping at the top of their cups) may gravitate towards high-necked or less constructed designs.
With eight bikinis in every style under the sun, you're guaranteed to find a cut you feel fierce in below.

01A Classic String Bikini
You can't go wrong with a classic string bikini. This one has an adjustable triangle top and low-profile removable pads for as much (or as little) coverage as you prefer. The side-tie cutaway bottoms are ruched and both are fully lined. Make sure you hand wash this one and let it line dry, as shoppers reported mixed results in the machine. One fan wrote, "This bikini is everything it's cracked up to be. I bought it based on the reviews of others who said it makes them feel confident. It's true!" She added for reference, "34A and I got the size small."

- Available sizes: 0-2 – 16-18
02A Ruffle-Trimmed Bikini
This cute bikini has a ruffle-trimmed top and bottoms have matching trim on the sides for a balanced look with a cheeky cut that's not too revealing. Some shoppers recommended sizing up, although one satisfied customer noted, "Fully adjustable top (straps, and the back closure) which is awesome when [your] top and bottom are never the same size." With that in mind, certain colors are available as separates so you can create a custom fit set.
- Available colors: 36
- Available sizes: X-Small – X-Large
03A Chic Bandeau With Removable Straps
A ribbed bandeau bikini reduces the potential slip-factor of a string triangle top. The lightly lined top comes with removable inserts and laces up in the back for a perfect fit — plus, it comes with an optional strap if you want more security. Just note the bottoms aren't fully lined, and have a very cheeky cut compared to other suits on this list. "34B and ordered a medium! It fits perfectly. The strappy back is sooo cute and pulling the bottoms up high on your hips makes your torso look bomb," one shopper raved. Another reviewer noted the quality, "I actually went diving in this suit and it held up super well so I think that's a pretty good testament to it."

04 A Lace-Up Bikini Top For Wide-Set Breasts Or Creating Cleavage
This high-quality string bikini top has a lace-front tie that's perfect for wide-set breasts since it lets you adjust the spacing for a perfect fit. The cups are molded with (unexpectedly cute) heart-shaped push-up padding on the inside for subtle lift and shape. "I normally wear 36B and bought a small," one reviewer prefaced. "It fits well. Nice feature of this top is adjustable strap in between the cups in the middle. So you can make it fit wider chest or tighten up for thinner chest. The padding is not excessive but enough for push up effect which is great!" Grab the matching side-tie bottom or full coverage bikini bottom for a complete set, or mix and match with your favorite.

05A Flowy Flounce Tankini Full Coverage
This tankini with a flounce top is a whimsical option for every shape and size. The flowy fabric glides over your frame for a sexy yet subtle look. High-waisted ruched bikini bottoms are vintage-chic and provides coverage. "I'm a B cup, but I have a booty...The top is fully [adjustable] and fits my bust well, despite my concern. The longest part of the top flounce just overlaps the bottoms, with midriff exposed on the sides and back. Comfortable [...] suit for a good price," one reviewer summarized. Choose from streamlined colors or more playful tasseled options.
- Available colors: 26
- Available sizes: Small – 3X-Large
06A Cute Halter With Cutouts
This high-necked bikini is a nice option if you sometimes experience gaping near the tops of bra cups. The halter top has soft removable pads for light shaping and the full-coverage bottoms feature a lined front. Choose from options with crocheted panels or plain fronts in solid hues and fun prints. One fan noted, "I love this two piece bikini. The color is beautiful and bright. The material is very good quality and soft. I love that the top has padding and the bottom has a protective liner. Size small fits my petite frame perfectly."
- Available colors: 14
- Available sizes: Small – XX-Large
07A Retro-Chic Wrap Bikini For A Secure Fit
This pretty bikini is the beachwear equivalent of a Diane Von Furstenburg dress, in a wrap silhouette that's classic yet modern. The tie-neck halter top has removable foam cups and wraps across the front once before knotting securely behind you. The ruched high-waisted bottoms are double lined for no show-through with moderate coverage on the back. "Nice material and sturdy fit. This does not move out of place! I am small chested (34A) and this top fits wonderfully," one shopper was thrilled to note.
- Available colors: 7
- Available sizes: 4 – 14
08A Push-Up Bikini With Ruching
This push-up swimwear set has underwire support and serious padding for a top that wears more like a heavy-duty bra with adjustable straps, although it has a traditional single clasp in the back instead of a sturdier band. The ruched overlay adds dimension and the lined matching full-coverage bottoms fit securely. "The top fit well and I did not have an issue with it slipping down even with the straps removed and didn't have an issue with not filling out the top (34B for reference). The bottoms are a bit tight but I expected that...you can't pick different sizes for the top and bottom," one reviewer explained, echoing others who loved the suit and wished for more sizing options.
