Bodies come in all shapes and sizes, so finding a swimsuit that fits perfectly can require a bit of searching. This is especially true if you have a large chest and you’re looking for a style that looks cute, will last more than one swim season, is within your budget and provides ample support. Luckily, we found the best swimsuits for large busts that have special features like underwires, shaping panels, wide straps, boning and molded cups that support and lift the chest.
At the Good Housekeeping Institute, we test and evaluate a variety of swimsuits in our Textiles Lab, including the best one-pieces and best bikinis. In the Lab, we analyze how well the swimsuits maintain their shape after being stretched, how they hold up to elements like seawater, the sun's UV rays and chlorine. We even consider online reviewers’ thoughts and enlist at-home testers to wear the swimsuits and share their opinions. Ahead, find the best swimsuits for large busts in 2025 to wear this summer at the beach and the pool.
Pros
Testers liked the flattering appearance
Durable materials
Thick, supportive straps
Cons
Only offers up to a DDD in cup sizes
Sizes: 6–18 with petite, long, plus, plus long and large cup-size options | Materials: Nylon and spandex | Colors: 7 (some limited stock)
Dubbed "most flattering" by our testers, this Lands' End swimsuit looks great on and is built to last. Wide straps support the chest, and there's a soft-cup bra inside for added coverage. The wrapped material and plunging neckline emphasize the waistline for a slimming effect, and the slightly compressive material smooths and shapes the stomach and hips.
The durable swimsuit held up to repeated washing in our Textiles Lab tests, showing no major changes in appearance, and it performed well in our colorfastness evaluations, so it should be able to withstand the elements like chlorine, saltwater and the sun's UV rays. This style comes in an assortment of sizes including regular, petite, long, plus and plus long with cup sizes available up to DDD.
RELATED: Best Plus Size Swimsuits, According to Fashion Experts
Pros
23 color options
Inexpensive
Provides ample support for large busts, according to reviewers
Cons
Color fades, according to some reviewers
Sizes: 6–18 | Materials: Polyamide, polyester, elastane | Colors: 23
Amazon shoppers can't get enough of this one-piece swimsuit with almost 13,000 five-star reviews, and it's available in 23 different colors and prints from simple black to bold leopard, so you're sure to find a style you'll love. It features a classic square neckline with wide straps that adjust in the back for a little more lift and a better fit, and there are removable padded cups.
The material is ruched across the stomach to hide any bumps or bulges. The brand says the swimsuit is suitable for cup sizes through E, but online reviewers with even larger cups said it offers plenty of support, with one describing it as "hands-down the best suit I've ever owned" and others sharing that it lasts all summer long. However, some online reviewers wrote that the color faded over time, especially after swimming in chlorinated pools.
Pros
Large size range
Design supports the chest
Stylish sweetheart neckline
Cons
No solid prints
Sizes: Band sizes 36–46 with cup sizes C–G | Materials: Nylon, spandex | Colors: 5
A tankini is a great option if you want a two-piece swimsuit but prefer more coverage. This one from Swimsuits For All is available in bra sizes from 36C through 46G and is equipped with plenty of support for your chest, including a built-in shelf bra, molded cups, an underwire, power mesh lining around the bust and adjustable straps. Online reviewers appreciated the support it offers. One said, "I absolutely LOVE how this bathing suit fits because I was able to select the right cup size with underwire support. I feel so attractive wearing this swimsuit."
It has a deep sweetheart neckline with ruching at the bust, and the top flares slightly towards the hips, so it won't cling to your stomach. While there are no solid colors, you can choose from five stylish floral patterns. Swimsuits For All carries a wide assortment of swim bottoms for a coordinating set, but we're especially fond of this on-trend swim skirt with built-in briefs.
Pros
Hook closure on the back for support
Impressive band and cup size range
Double-layered cups
Cons
Only available in two colors
Sizes: Band sizes 30–40 and cup sizes D–K | Materials: Polyamide, elastane | Colors: 2
While it's easier to find bikinis with bra sizing for large busts, it can be difficult to find a one-piece swimsuit. This one comes from Panache, one of our favorite bra brands for larger cup sizes, and the swimsuit is available in sizes 30D through 40K, though it's only available in two colors.
It has hidden underwires, built-in double-layered cups and a hook closure in the back for extra chest support. The straps have gold hardware, there's a chic ruched detail at the bust and we love the princess seams that run down the swimsuit, creating an hourglass effect.
Online reviewers with large cup sizes said this swimsuit is key to feeling confident at the pool. "I have never in my life owned a swimsuit that was so perfect," shared one reviewer. "The material is durable, high quality and chlorine resistant. The structure is supportive and slimming."
Pros
Extensive size range
Lace-up back allows for adjustability
Buit-in underwire for support
Cons
Online reviewers have difficulty finding the right size — so many options
Sizes: XS–4X with cup sizes A–J/K and short and extra-long torso options | Materials: Nylon, spandex | Colors: 3
TA3 went viral on social media for its waist-cinching styles that transform your body. The Lifty swimsuit has shaping panels and a lace-up back that can be tightened for an hourglass look (or loosened if you need more breathing room!), along with underwire cups to support and lift the chest. It's available in sizes XS through 4X with cup sizes A through J/K to accommodate larger chests, and it comes in short, regular/long and extra-long torso options. Because there are so many sizing options, some online reviewers have had trouble finding the right size and recommend ordering a few options to try out at home.
Online reviewers with big busts highly recommended the swimsuit. One shared, "It holds me in in all the right ways and looks so flattering! This is by far my favorite swimsuit of all time!"
Pros
Trendy one-shoulder design
Standard and long torso options
Tons of colors and patterns
Cons
No padding or cups
Sizes: 0–24 | Materials: Recycled polyamide, elastane | Colors: 15
This super popular swimsuit from Summersalt is one of our top-tested styles and is one of the brand's best sellers, loved by women of all ages, shapes and sizes. The brand took 5 million body measurements to inform the fit of the swimsuit, which is available in sizes 0 through 24 with standard and long torso options. That way, the suit can fit tons of body shapes and sizes, including small and large busts.
One GH analyst who wears this style says the material is compressive without feeling too tight, so it smooths and shapes but doesn't feel restrictive. She said, "I've had it for years, and it still looks great. The colors are just as bright, and the swimsuit hasn't lost its shape." Online reviewers said the swimsuit is worth the $95 price tag, describing it as "the best investment" and sharing that it's "worth every penny."
We love the iconic color-block look, but the brand also offers the swimsuit in solids like black and olive, as well as delicate prints and patterns, and there are variations with fun details like bows or cutouts.
Pros
Straps are convertible and removable
Large range of band and cup sizes
Available in 11 colors
Cons
Pricey when not on sale
Sizes: Band sizes 30–42 and cup sizes D–I | Materials: Recycled nylon, spandex and polyester | Colors: 11
We rated Bare Necessities as the best swimsuit brand for large busts and we especially love this bikini option. Available in 11 colors and a wide range of band and cup sizes, you can find your perfect color, fit and look with this convertible bikini top. The straps can be worn the standard way, criss-crossed or you can forgo them and go strapless. Keep in mind that the wrap design on the cups remains the same (only the straps are convertible).
Crossing the straps in an x-shape in the back can provide more support for larger busts, similarly to the straps on some sports bras. And if you’re lounging at the beach and want to prevent odd tan lines, simply unclip the straps for bare shoulders. The twisted balconette top has side boning and foam-lined underwire cups that can help with supporting, lifting and shaping the bust, all while remaining comfortable. Birdsong's Sash Fold-Over Bikini Bottom has a similar wrap appearance that pairs will with this bikini top. As much as we love this bikini top and the brand's bottoms, it is a bit pricey when it's not on sale.

Pros
Trendy patterns and textures
Large triangle cups
Extensive size range
Cons
May be variations in sizing and color depending on fabrication
Sizes: S–VVV and petite | Materials: Nylon, Lycra | Colors: 19
If you have a large bust, it can be difficult to find a classic triangle-style bikini top with panels that are actually big enough to cover your chest. Monday Swimwear's Morocco Top features a triangle style with adjustable neck and back ties, and it comes in V (Voluptuous), VV (Very Voluptuous) and VVV (Very Very Voluptuous) sizing to fit curvier frames. There's chic gold hardware for an elevated look, and we love this pleated style with a bit of crinkle texture. Available in 19 colors, the pattern options for this suit are more modern than other swimsuits for large busts.
The brand also carries other bikini tops and one-piece swimsuits designed to fit larger busts, along with tons of coordinating bottoms including super stylish sarongs and coverups. As much as we love this bikini, it's undeniably pricey for one half of a swimsuit, but it's a good investment if you're looking for a high-quality, trendy bikini top. The brand does note that there are sometimes slight variations in color and size compared to the images and product description online, but there is a 30-day return window for full-priced items.
Pros
Slimming effect
Durable and resists fading
Underwire provides extra support
Cons
Limited size range
Sizes: 10–18 | Materials: Nylon, Lycra | Colors: 7
Similar to your favorite shapewear, Miraclesuit's Oceanus swimsuit is made with material that sculpts and smooths your stomach and hips. When we evaluated slimming swimsuits in the Textiles Lab, we found this ruched swimsuit slimmed more than other styles. It proved durable in our tests as well, resisting fading after being exposed to seawater, chlorine, sweat and more. We love the look of the deep-V neckline and appreciate the built-in foam cups with underwire for some extra lift and support.
While the size range is limited, it's a great option that goes up to a size 18. One happy online reviewer shared, "My 40 DDs were secured... and I had a nice waistline." This style is suitable for DD-cups, but the brand also offers a DDD-cup option, along with its standard and plus-size versions.

Pros
Stretchy enough to wear throughout your pregnancy and beyond
Contracts to original shape
Padded cups for coverage
Cons
No underwire
Sizes: XS–XXL | Materials: Polyester and elastane | Colors: 5
Here at GH, we love Seraphine for their maternity dresses, clothes and swimsuits. The material of this style is super stretchy, so it’s designed to expand with your body — belly and breasts — as you grow during your pregnancy, and it can be worn postpartum because it will retain its original shape. That way, the swimsuit won't go to waste after you give birth and are no longer pregnant (genius!).
While this suit doesn’t have an underwire, it does have a shelf bra and padded cups for coverage. The wide straps are thick and supportive and the tactile crinkle texture creates a ribbed appearance.
Abercrombie & Fitch Curve Love High Apex Underwire Bikini Top

Pros
Impressive band size range
Supportive underwire
Designed specifically for large cups
Cons
Cup range is limited
Sizes: XXS–XL | Materials: Nylon, elastane | Colors: 3
Not everyone with a large chest has a large band size. Abercrombie & Fitch's Curve Love line is made just for those who have smaller band sizes and larger cup sizes (28D through 42DD) and includes bottoms with a little extra room in the hips too. This unlined top has darted cups and a gusset (the piece of material between the cups) similar to a bra, which helps the swimsuit lie flush with your chest, and there's an underwire for support. The Mid Rise High-Leg Moderate Bottom has 15 colors (including the same three available for the bikini top) if you want to match or mismatch.
One online reviewer said this swimsuit is a "game changer," and a DD-cup wearer said, "I can’t say enough how much I love this bathing suit... I could not be more happy about the fit and comfort." Some sizes are currently out of stock in certain colors, but luckily you can browse similar tops in the Curve Love line.
Pros
Wire-free style is still supportive
Tons of colors
Free virtual sizing service
Slightly compressive fabric
Cons
Lacks padding
Sizes: XS–XXL | Materials: Nylon, polyester, Lycra | Colors: 19
When you have a larger chest, it can be difficult to find a plunging swimsuit that's supportive and won't lead to slippage. Left on Friday's Sunday Top (and the rest of its Big Boob Tops) is specifically designed for those with D through G cups, so you can wear the low-cut style worry-free. It's made with smooth, slightly compressive fabric that holds you in place and has adjustable straps for lift. There's no underwire or bulky padding, but the swimsuit is lined for a little modesty.
Though pricey, one online reviewer with a 36G bra size was impressed by the wire-free style. She said, "I haven’t worn a swimsuit top without underwire in years, and I’m so glad I took a chance on this! It’s comfortable! It’s supportive! It’s cute! Can’t wait to wear this all summer!" With over a dozen fun color options including Neon Pink and Cold Brew (brown), the brand encourages you to mix and match your bikini top with one of its bottoms including high-waisted and low-rise styles. Note that certain colors have limited sizes available, so we recommend shopping this top ASAP if you have a color preference.
If you're struggling with sizing or choosing the right style for your body type, the brand offers a free virtual concierge service.
Pros
Ruched stomach
Tons of colors
Long-lasting
Cons
Not much coverage in the bum, according to some reviewers
Sizes: XXS–XL and 16–26 Plus | Materials: Nylon, spandex | Colors: 27
Loved for its affordable and fashionable styles, Tempt Me is a popular swimsuit brand on Amazon, and this style has more than 25,000 five-star reviews. This high-neck style is also a favorite of GH analysts and testers. We had 10 women with different body types try this style, and all 10 of them described the swimsuit as "flattering." They loved the ruched stomach, high neckline, mesh inlay and plunging back details.
However, some online reviewers said there was not much coverage in the bum area, especially on fuller figures. One GH analyst who has worn this style for years says it offers a great bang for your buck and is impressed by how well it has held up to regular use with only minor signs of wear.
Pros
Looks like a tank top
Interior cups for coverage
Adjustable straps
Cons
Limited cup sizes
Thinner straps
Sizes: XXS–XL | Materials: Recycled nylon, nylon, Lycra | Colors: 4
Athleta's athletic wear regularly comes out on top in our tests of the best workout clothes, and its swimsuits are perfect for someone looking for a style that goes beyond lounging at the pool. This tankini top is made for D and DD cups and has a longline design with a little more coverage, so it won't ride up while you're paddle boarding or riding the waves. "I love this tankini, it is comfortable to wear all day, adjustable and has decent support," one online reviewer said.
The straps are on the thinner side, but they're adjustable, and there are cups inside for shaping and coverage. Plus, it's made of a pique material, and you can pair it with matching high-waisted bottoms for a textured set that's totally on-trend.
Pros
Extensive band and cup size range
Provides great lift, according to reviewers
Seamed foam cups for coverage with comfort
Cons
Some customers disliked the bra-like appearance
Sizes: Band sizes 30–42 and cup sizes D–G | Materials: Polyamide, elastane | Colors: 6
Known for its bras available in larger cup sizes, Freya is one of our top picks for women with DD+ cups. The brand's bikini tops are similar to its bras, featuring quality construction and elements like an underwire, seamed foam cups and boning along the sides for structure and support. They're available in standard bra sizing ranging from 30D to 42G, and online reviewers with large busts said the suit fits perfectly and provides great lift and comfortable coverage without excess padding or bulk.
One reviewer shared that she loved that she "can show off some skin and still be [supported]." She added, "The fabric is high quality, and I feel sexy and stylish in it." Two reviewers said they felt that the swim top looked too similar to a bra, but others loved the bikini top's appearance. You can pair it with the brand's bikini bottoms with matching colors and patterns.
