The 22 Best Swimsuits for Small Busts, According to Reviewers and Swimwear Experts

Stylest's swimwear-meets-shapewear is a low-key vacation wardrobe revolution. This suit has chest support and all-over shaping—but it doesn't look anything like typical shapewear. In sum? It's a suit that feels and looks amazing.

Sizes: XS–2X

What reviewers say: "Dream come true! The suit pulls everything in while still being comfortable. The square-front style is elegant and sexy. I absolutely love the color—so vibrant. Couldn't be happier!"

Summersalt's plunge one-pieces are made with a luxurious compression fabric, so you won't sacrifice a no-slip fit for a gorgeous neckline. In addition to straight sizes, there are also extended torso options for taller shoppers with small busts. But the thing that keeps other shoppers coming back for this best-seller are the 17 combinations of prints and solids with a wrap-dress effect.

Sizes: 2–22

What reviewers say: "This is probably the best bathing suit I’ve ever owned. The quality is superior to many other bathing suits. The fit is extremely flattering as well. I feel very confident wearing it.If you’re between sizes, like I am, I would size up.

Whether you're swimming laps or wading into the shallow end, you'll want a square neck suit like Andie's best-selling one-piece for more active days. The higher cut leg and lower neckline are secure, yet flattering.

Sizes: XS–XXXL

What reviewers say: "The design is super cute, it’s not too revealing- it has the right amount of sexy with the cut and the design itself. The material is thick but in a good way. I got the medium and it fit me perfectly—hugs me in the right places. I love the ribbed eco texture- it’s not a typical swimsuit. I love my first one so much in 3 days I bought another one!"

Plunge swimsuits have the same level of support as triangle bikinis—just with a little more skin showing. The space between cups makes them particularly suited to shoppers with wide-set breasts. This black Lively plunge bikini is a forever take on the silhouette: minimal and refined.

Sizes: XS–XL

What reviewers say: "This is super cute and I was honestly blown away by the amazing support. I was able to jump and run around and everything stayed in place! Extremely comfortable, I felt like just wearing it as a bra all day! I am so happy with this purchase and can't wait to wear it this summer. Really glad I found a good quality swim top that is also adorable!"

You'll never have to worry about a Tropic of C bikini falling out of style (or, you falling out of it). Model Candice Swanepoel's swimwear label is all about essential colors, cuts, and eco-friendly fabrics meant for wearing on vacation for years.

Sizes: XS—L

Underwire styles aren't just for bikinis. If it's structure and full-body coverage you're after, a one-piece like Tory's Burch's belongs in your cart.

Sizes: XS–XL

What reviewers say: "This is one of the most flattering swimsuits I've ever worn. I have a small bust (30B) and was worried the cups wouldn't fit, but there is no gaping and it fits beautifully. I actually love the amount of structured padding, as well—it gives me a bit of extra shape where it's needed. The only thing I don't love is that it feels a bit tight pulling the bathing suit up around my hips, but once on, it's perfect. It also stays in place without the straps, which is also amazing. I am a convert and will be looking for new patterns each season going forward."

Square neck tops may be suited for water sports, but they're not all technical fabrics and solid colors. Case in point: The fun ruffled straps and modern botanicals on Agua by Agua Bendita's latest bikinis.

No matter your bust size, scoop neck swimsuits are universally comfortable (and supportive) options—minus the padding or boning other silhouettes require. This low-coverage scoop neck is an easy on and easy off, with fabric resistant to fading or snags.

Left on Friday also has tall sizes for sunbathers who need a little extra length in the torso.

Sizes: XS–XXL

What reviewers say: "This swimsuit is adorable. I love the cutout under the chest because it adds detail and support for my chest. The bottoms are a little cheeky, but not to the point of discomfort, and very flattering. The material feels like it is holding me in, but it’s not restricting."

Marysia's Dobrzanska Reeves suggests extra details like ruffles, extra pleats, or shirring for a triangle top to accentuate your look. "I love the Broadway top, a classic triangle shape with our signature scalloped trim, for smaller busts," she says.

Sizes: XXS–XXL

Sizes: XS–XL

Of the three top styles in Cuup's swimwear line, The Plunge is a top-choice for small busts, chief design officer Pascale Gueracague tells us. The reasons? "It is minimal. It's designed without excess bulk, includes a lighter lining fabric and underwire support, and has a plunging deep-V that celebrates a beautiful neckline and natural shaping."

This one-shoulder swimsuit has an average rating of 4.6 stars and glowing reviews from shoppers with small busts to match. (But for anyone reading at an in-between size, reviewers say Beach Riot's suits are great for larger chests too.) It's unlined for a barely-there feel and comes in 11 shades of the softest ribbed fabric.

Sizes: XS–XL

What reviewers say: "I was hesitant to order this online because most one-piece suits don’t fit my long torso. But this one fits perfect! The color is beautiful too."

Vitamin A's underwire bikini has all the same support as more minimal styles—plus, a range of prints and textures to try out in addition to beachy neutrals. If you like the fit as much as other shoppers, you may just buy two of the exact same suit.

Sizes: 4–14

What reviewers say: "I've been looking for a supportive under wire top that's cute and comfortable, and so happy to have found the Demi. I love that the tie in the back is adjustable and the fabric lays on the skin and doesn't cut in. Definitely will be doubling this piece as a bra too."

When you wear Jade Swim's asymmetric strap on your shoulder, it'll stay in place even in the biggest waves. Then when you're working on your tan, you can fold the strap down to create a bandeau.
