If you're a grown woman with a large bust, you KNOW why I had to write this post! Google swimsuits for large busts and you'll have plenty of articles but they feature styles that are no match for grown-women breasts that have led adventurous lives. I know myself, the large bust swimwear I wore in my 20's and 30's covered but would be no match for my breasts now. So here are the best large bust swimsuits for grown women.

What Makes Large Bust Swimsuits for Grown Women Different?

I say any woman, any size, any shape, any age, any anything can wear whatever she darn well pleases. There is nothing more stylish than confidence, and we deserve to wear what makes us happy and feel good. But I know as a grown woman who has nursed a baby, experienced weight fluctuation, activity and fitness changes, and has a few decades under her belt has different swimwear needs from when I was younger:

  • Support: I don't need my breasts to be up near my neck, but I don't want them down near my belly button either. I desire a swimsuit that will have my breasts somewhere close to what I get with my favorite wireless bra.
  • Coverage: I am still sexy, but I know as a grown-ass woman I don't need to expose all of my skin to look great. I feel more confident when I have more coverage over the breasts, the rear, and like a higher-waisted bottom if I choose a two-piece.
  • Function: Sure, I sometimes just want to lie on a lounge chair or float and relax, but I don't want to have to constantly adjust myself if I choose to have some fun activity in the sun. And I want my suit to still function once it gets wet (we've all experienced swimwear that sags, bags, and turns transparent when in contact with water).
  • Style: I want a swimsuit that looks stylish, even though I have a large bust and desire support and coverage. I deserve cool prints, tasteful silhouettes, and on-trend details but fashion that looks cool on a grown-ass woman.
  • Size Range: I spent my college and young adult years in D-cup bikinis from popular retailers and they worked well enough. Now that I am a grown-ass woman, I know that a true swimsuit for large busts needs to be available beyond a D cup. It needs to offer a variety of band sizes, and bottoms need to be offered larger than an XL. Grown women come in a range of sizes and shapes, and suits needs to have a good size range to accomodate many of us.

The Best Large Bust Swimsuits for Grown Women

Now, not all grown women desire the same sort of swimsuit. We know what we want and what we need. For some, we want a large bust swimsuit for swimming laps, for others we want a large bust bikini for catching rays. We may desire a large bust swimsuit for activities like stand-up paddle boarding or kayaking, or just want a swimsuit that can contain our bust while we chase around our kids or grandkids.

Below I separate the best large bust swimsuits for grown women by specific desires for bathing suits, and share why I chose these swimsuits over many others. There are more than 25 different styles, some from brands you are familiar with, and some that may be new to you. And if I own any of these swimsuits, I will share a photo of me in them (for reference, I am 5'3″, a size 14 and wear a 36 F/G or 38 DDD bra).

To make it easier to toggle to the category of large bust swimsuit you desire, I have made a table of contents:

The Best Large Bust One-Piece Swimsuits

When searching online for one-piece large bust swimsuits I am surprised by how many claim to be large bust, but don't have cup sizing and think a simple shelf bra will get the job done! When ordering one-piece swimwear in the past, I have found many suits too short for my torso because I need to take so much fabric for my bust. That's ridiculous, considering I am 5'3″! So these one-piece large bust swimsuits are made for truly large busts, offering extra fabric, underwires, soft or molded cups, seaming, and more to accommodate as well as support breasts:

1. Fantasie Twist One-Piece Swimsuit

By the end of this large bust swimwear post, you will tire of hearing the brand Fantasie. But as someone who has owned many suits from this brand, Fantasie truly knows how to design for a large bust. The “Twist” suit is their most popular one-piece, available in a range of patterns, solid colors, and even versions with tummy control. Available in bands 32-42 and cups D-GG, I have found The Twist has worked when I was a size 10 and when I was a size 16. The back is low enough to look classic but high enough to provide support. The straps are adjustable and just wide enough to hold everything up. And the leg openings are adjustable with adorable ties on the sides.

The details make this large bust one-piece chic and luxe

2. Panache Anya One-Piece Swimsuit

Available in bands 30-40 and cups D-K, this suit is made for large busts but isn't like wearing a suit of armor. Double-layer balconette cups support and lift your bust, a back closure for additional support, and adjustable straps will keep you contained and comfortable. Elegant with luxe details, the Anya one-piece from Panache is a classic that is begging to go on your next vacation.

Classic, chic, great size range, and some styles made from recycled fabric!

3. Bravissimo Amalfi One-Piece Swimsuit

For those who desire coverage and support without the padding found in most large bust swimsuits, this one-piece is a great choice. Bravissimo is a UK brand that focuses on lingerie, sleepwear, swimwear, and clothing for those with a large bust but has easy shipping and returns for US customers. With a wired bra, adjustable straps, and a clasp in back for additional support, this one-piece comes in band sizes 28-40 and cup sizes D-K and a range of colors and sizes.

4. Birdsong Wrap Underwire One-Piece

If you love the wrap look of the Summersalt swimsuit, but like me didn't find it supportive enough for a grown woman's large bust, this suit from Birdsong is a great alternative. Available in two colors this season (though previous seasons have had different colors and prints), this suit comes in sizes 8-16 with cup sizes from D/DD to J/K.

5. Miraclesuit Oceanus DD-Cup Swimsuit

This is a classic favorite for slimming the body, but I always felt that Miraclesuit didn't cater to truly large busts. However, I owned this suit and the DD-cup version fit my F-cup breasts comfortably while giving them a great shape. Available in sizes 10DD-18DD, if you usually go down a size for swimwear I recommend going with your regular apparel size for Miraclesuit; you'll still get compression but it will be easier to get on and off.

The Best Large Bust Tankinis

If you desire your midsection to be covered, but like the ease and custom sizing of separates, a tankini is for you. Tankinis are also great for those who have a longer torso as a tankini can look chic even if there is a bit of skin between its hem and your swim bottom. Tankini tops are also great when you wish to wear board shorts or have more of a “beach to street” look. Below are the most stylish tankinis for large busts that I found that are great for grown women:

While I don't own this tankini top, I've owned several separates from Sunsets and find the fit and quality stellar.

1. Sunsets Muse Halter Underwire Tankini

I have owned several swimsuits from Sunsets over the years and appreciate the combination of style, support, and quality. I've had my Sunsets suits in chlorine, in saltwater, sat on concrete, let them bake in the sun, and they have even gone in the dryer by accident and still look and perform great.

Available in sizes 34D to 40 G/H and in a range of colors, this is a great tankini top. The halter neck is sexy but also customizable for shorter torsos or if you need a bit more support. The cups are molded with removable foam inserts and the clasp in back provides additional support. Sunsets has a great range of coordinating bottoms from low-rise bikinis to high-waisted bottoms and stylish skirted options up to size 22W. Though I'll admit from owning this line, it's classic swimwear fabric so don't hesitate to style this tankini top with your favorite solid-colored bottom from another retailer!

2. Profile by Gottex Tutti Fruitti Tankini

If you are looking for a simple but elegant and supportive tankini top for large busts, the Tutti Fruitti from Profile for Gottex is a great choice. This tankini top has a hidden bra with foam-lined underwire cups and two-hook and eye closure and wide adjustable straps that don't look frumpy. The torso is shirred which offers modesty and camouflage and the entire tankini top is double lined for opacity and a bit of a slenderizing feature. Available in bands 32-40 and cups D-G. Click here for the coordinating bottoms which offer a range of coverage and modesty in sizes 6-16. While not available in cup sizes, this tankini top also comes in plus sizes 16W-24W.

3. Lands' End V-Neck Wrap Underwire Tankini

This tankini top has been a Lands' End staple summer after summer for years because it's a customer favorite and a classic silhouette. This tankini has adjustable straps, underwires, and removable soft cups. The bodice is double lined for modesty and a bit of a slimming effect. Available up to a DDD cup in a variety of prints and solids, Lands' End also has a great range of bottoms that are classic, skirts, and shorts in a range of coverage and modesty. Lands' End suits last; I have some that are several years old and still look and perform like new.

The Best Large Bust Bikinis for Grown Women

I love a bikini, they're sexy and fun and let's be honest, a lot easier when you need to use the facilities! As someone who is a different size on top from the bottom, and someone who has a short torso, bikinis often give me a better fit than a one-piece. And with a higher rise bottom, there isn't a ton of skin exposed on the midsection. Below I share the best bikinis for large busts that I found on the internet, with details perfect for us grown-ass women.

1. Elomi Magnetic Bikini

When looking online for the best bikini tops for large busts and cup-sized bikini tops, the Elomi Magnetic was recommended over and over for looking great, providing good support and coverage, and staying in place even if you're active. With close-set adjustable straps, 4-part mesh-lined cups, and bra-inspired details, this is a top that is quality. While Elomi has several coordinating bottoms, the fabric will also match with most any swimwear bottom in your collection! Available in bands 34-44 and cups E-JJ.

2. Smart & Sexy Swim Secret Halter Bikini Top

I feel confident recommending this bikini from Smart & Sexy because I own it! That's me above last summer at Fire Island. Available in 34C to 44DD and a fabulous range of on-trend colors and prints, this bikini top is budget-friendy while offering a lot of support. The second strap is removable so you can add it for interest or remove for a more classic version. It's from classic swimwear fabric so you can wear with any bottom of your choice; Smart & Sexy also has a bunch of different swim bottoms to choose from up to size XXL (I have this one). Heads up, I found the cups ran big (see my initial review). It seems others in reviews also found this top runs bigs in the cups.

3. Bravissimo Budapest Bikini

This bikini top from Bravissimo has subtle details to make it a great choice for those with a large bust. The front straps are double to provide support from multiple locations and they are adjustable in back. The cups are unlined, but shaped and wired for lift. And this sultry snakeskin print is available in band sizes 30-40 and cup sizes DD-K. Bravissimo offers two matching swim bottoms on the same page so you can choose your coverage, or style this black printed top with a solid black bottom in your wardrobe!

The Best Trendy Large Bust Swimsuits

Who says grown women have to only wear wide straps, cabbage roses, leopard prints, and frumpy skirts? There are plenty of trendy and stylish swimsuits for large busts out there that truly support and provide coverage. Below I share my picks for the best trendy large bust swimsuits for grown women:

If the bikini bottoms in this photo aren't your jam, I've linked to the brand's range of different options that have far more coverage.

1. Birdsong One-Shoulder Underwire Bikini

Available in a range of prints and solids, this top has the on-trend asymmetrical silhouette for bands 32-38 and cups D-I. This bikini top comes with a removable second strap you can have straight or crossed in back for additional support The top is sold separately from the bottoms, and Birdsong has a range from cheeky side-tie bikini bottoms to full-coverage and skirted options in sizes S-3X. I linked to this suit at Bare Necessities, which has a great selection, lots of customer reviews, and reasonable shipping/return policies.

2. GabiFresh Tie Front Underwire Bikini

While many recommend Swimsuits for All for large busts, few of their suits are truly designed to support a heavier large bust. However, Gabi Fresh's collection at the retailer has a few cup-sized swimsuits, and this adorable striped number gets rave reviews for fit and style. Trendy and stylish while still offering plenty of coverage on top and the bottom to look great but also have fun in the sun. While you have to buy the pieces together, you can still choose different sizes for top and bottom. Available in sizes 10-26 and cups up to G/H.

I love the bold colors, the true support, and the wallet-friendly price!

3. Smart & Sexy Long Lined Underwire Bikini Top

With the same support as the previous Smart & Sexy bikini I featured, this version has a longer profile that is inspired by lingerie while also offering a modern look. From neons to bold prints and classic colors, you are sure to find one that works with your personal style aesthetic. Available in sizes 34C – 44DD; tap here for coordinating bottoms available up to XXL.

4. Pour Moi Bow Front One Piece

The cut-out trend is very popular this summer, but it's a tough trend to wear if you have a large bust, and many cut outs may not be where us grown-ass women will want them. This suit from Pour Moi feels youthful, has a modest bust cutout, but offers tummy compression in bands 32-38 and cups B-G. Mesh-lined underwire cups with slings and adjustable straps means this swimsuit will give your bust the support you need without sacrificing style.

The Best Large Bust Swimsuits for Swimming Laps, Paddle Boarding, and other Water Activities

A lot of companies that carry swimwear for laps and water activities carry maybe up to a C or D cup, but usually the size selection is limited for both bra size and apparel size. However, I found some winners and think these are the best large bust swimsuits for fitness and water activities:

Looks just like the swimsuits for those with small busts but has that extra support we need

1. Freya Freestyle Underwire One-Piece Swimsuit

This suit is designed for performance, and reviews across the web at different retailers claim it's supportive, survives seasons in chlorine and saltwater, provides compression without discomfort, and will hold you in place as you dive for that volleyball, dive and do kick turns, and surf the waves. Adjustable straps for length and whether straight or crossed, snap back closure, and molded underwire cups. I've linked to Bare Necessities which has the biggest selection of color and size and a good shipping and return policy. Available in two colors, band sizes 30-40 and cup sizes D-H.

2. Speedo Premiere Ultimate One-Piece Swimsuit

Speedo is the go-to brand for swimmers, but they have few suits that are made for large busts. The Speedo Premiere Ultimate however, is made for a range of bust sizes and gets great reviews for fit, support, and performance. Available in three colors, band sizes 30-38 and cup sizes E-K.

3. Lands' End Tugless Tank

If you want a classic suit that can go from swimming laps to sunbathing, looks chic with a sarong but will stay in place as you chase after kiddos or chase the next wave, the Lands' End Tugless Tank is a smart choice. It comes in sizes 2-16, up to a DDD cup, long and petite options, a mastectony option, and a tummy slimming option. The leg openings are low enough to hold everything in, but high enough to not look frumpy. While I have it in classic black, it comes in a great range of solid colors and prints. It will hold up to chlorine, salt, and sun and is a classic, chic, and stylish option for most anyone.

If you want support and coverage, but prefer a two-piece, may I recommend this sports bra-inspired bikini top from Sunsets. I own it and can attest to it being supportive and holding everything in even if you bodysurf or do flip turns. It looks like a classic sports bra, but has foam cups, underwire, side boning, and adjustable straps you can wear straight or crossed. Available in band sizes 28-40 and cups D-I for tops and a range of coverage options for matching bottoms, which are available in sizes XS-2X, this is a suit I will be wearing my third summer and it still looks and performs like new.

Some swim dresses look frumpy, some look vintage cute, and some just look clean and chic. And I think this swim dress from Lands' End is elegant with clean lines and a square neck, you can pretty much go straight from the beach to the beachside cafe. Undershorts mean you have great coverage even if you bend over or swim laps. The misses option comes in a D-cup with regular and long lengths; the plus size option comes in a DDD cup version.

This swim dress from Miraclesuit comes in a regular option and a DD option, but multiple reviews state that the “regular” version is also quite supportive for large busts.

This link goes to a variety of colors and prints of this suit and the misses options in sizes 10-18 and plus options in sizes 18W-22W.

The Best Plus Size Large Bust Swimwear

While many of the styles above come in plus sizes, these suits are designed for both plus sizes and those with D-cup and larger busts:

This is the swimsuit that so many retailers carry that look great on the skinny small-busted models but once on, there just doesn't seem to be enough coverage where you want it. Not so with this swimsuit from Lands' End which comes in sizes 16W-24W and up to a DDD cup. Designed to lift and smooth, Lands' End claims it will make you look as size smaller while offering soft cups to shape and support your bust.

  1. Thank you! I read a bunch of other articles re swimwear for busty women and they were laughable. No one seems to get that we need real engineering because–gravity! So thank you for this, especially because you’ve actually tried it many of these suits. It’s so challenging to find a cute suit that actually supports H cups. One challenge I find is that I like compression in the bust as well as underwires but most brands don’t have that.

  2. It’s a UK brand but Deakin and Blue might be worth putting on your radar – they’re a small woman-owned business and sizes go to an HH cup and up to a UK size 24.

  3. Such a great roundup! For anyone who goes a bit higher in the alphabet – Lands’ End usually has a few items that go above DDD. I have a tankini in G cup, which is a tad smaller than I wear in bras but works well. (And as with most LE items, it holds up well; mine is at least 5 years old and still looks great.)

  4. I usually only lurk on this website, but I had to comment after buying the best swimsuit last July. It is the curvy kate rhapsody bandeau swimsuit. I am fairly large on top (H cups), and the mesh panels are customizable for comfort or style. The ladies always felt secure. Love!

  5. Thank you so much for sharing real women in swim suits. Nothing deflates confidence like seeing a twiggy girl rocking a swim suit made for bigger girls.

  6. Am I the only large-busted woman who hates that it is so difficult to find a swimsuit without cups? What I want is a band under the bust, a nice tight fit and everything squashed down nicely, and then I can swim. I pretend I’m invisible when I swim (really don’t want to think about my thighs and stomach) and whether in a pool or the sea, I want to swim and jump about. Come out, and I just want to dry and change. Who wants to lie around in the sun in hot nylon getting burnt? Much nicer to change into summer clothes and possibly a hat, and lie under a tree with a book. But those cups – just so annoying. All that extra fabric. By the way, I am 66 and a British E cup. One of my friends said that a swimsuit without cups is uncomfortable, but I just don’t get it…

  7. 10/10 endorse the Smart & Sexy Longline Bikini Top. I have it in hot pink and black with a cherry print. They’re super supportive and incredibly comfortable. I love the wide back band both for the support and the
    aesthetic proportion.

  8. As always, you come just in time. I don’t love kayaking and hiking in my underwear under UPF rated leggings and a shirt. Undies just don’t dry the same. Not to mention what the saltwater will do to the fabric. I’ve already got that sports bra top in my cart. Now to find a great suit for vacation. Thanks Alison!

    Figleaves offered excellent bra sized swim wear but alas, they’ve gone out of business.

  9. Alison! This information is a home run! Thank you so much for doing the research and putting together this list. I’ve always purchased Land’s End Tugless Tank and Underwires Wrap Tankini so this article 1) verifies my thinking and 2) gives me some other options. 🙂

  10. I’d like to recommend Wild Isles swimsuits. Small business, women-owned, no underwire, sustainably sourced fabrics – and the best swim wear I’ve ever owned. They cater to D cup up toe H and bottoms to size 24.

  11. Hi! Thanks for this article. In your research, did you happen to come across a one-piece with long sleeves? Thank you!
