If you’re the proud owner of DD+ boobs – which happens to be the average UK size – you’ll know that finding the best swimwear for big busts that actually fit amounts to a Herculean task. Most brands don't cater to fuller bust cup sizes bigger than a D, and many now sell bikinis as a set – something which proves fairly unhelpful if you're different sizes on top and bottom, as many are.

That's why, as someone with an H-cup who often struggles to find bikini tops, I decided to investigate what's actually out there. Thankfully, I discovered a wealth of brands that are entirely invested in selling high-quality swimwear for big boobs.

How do you find supportive swimwear for big boobs?

I've always gravitated towards brands like Freya and Bravissimo, both of which are renowned for catering to bigger bust sizes. Recently, however, I've realised that there are other brands giving great swimwear – you just have to know where to find it. That's where I come in. For example, I recently found a fab bikini which fitted perfectly and was – wait for it – from Abercrombie and Fitch, a place I hadn't thought to visit since I was a teenager. I can’t tell you how happy it makes me to see high street brands - even the ones you thought would never change - evolving to accommodate more sizes and shapes.

I also really like a brand called Ivory Rose, stocked at ASOS and tend to find a lot of affordable bikinis and one pieces there. The only snag is that, due to the fact the fit is great and it's not really expensive, pieces tend to sell out really quickly.

Best overall swimwear for bigger busts

The reason I've named this as the best overall swimwear for bigger boobs is because I was so surprised to find a bikini which fitted perfectly at Abercrombie (I went for an XL). This is probably why much of the brand's swimwear has already sold out, so the red bikini I enjoyed so much is sadly no longer available. I've also bought this top, however, which I'm planning to mix-and-match with bottoms I already own. I found that this is really supportive and gave a really nice shape, too.

Here are the matching bottoms if you want to go for the full set. The sizes go up to an XL, which is the equivalent of a UK 18-20.

Best one piece swimsuit for bigger busts

Hannah Banks-Walker, Grazia's head of fashion commerce, tried this last summer and hasn't looked back. 'My bra size is usually a DD and I have found it tricky to find really flattering swimwear in the past. This one piece, however, has a built-in bra shelf, so feels extra supportive. It also has a really flattering cut – you can remove the belt if you want to – and generally made me feel really confident. I'd recommend measuring yourself according to the brand's size chart to make sure you really get your best fit.'

Best bikini for bigger busts

Jade Moscrop, Grazia's commercial content editor, says: 'This bikini went viral on social media thanks to the sheer amount of women praising its ability to flatter and support bigger boobs. I'm not usually one to take much notice of 'viral' items and, having just had a baby, can't say that swimwear was top of my shopping list. But I have to say, all of those women on TikTok were right: it really is a fantastic bikini. Super-flattering, it still feels really stylish, so doesn't make me feel like I'm having to shop from a crap selection of swimwear just because I have a slightly bigger bust. I would recommend this to everyone.'

Designed for cups B-G | Full coverage cups | Comfortable underwire | Adjustable straps

Best underwired bikini for bigger busts

I could bang on about Skims forever; the brand has nailed great fit with inclusive sizing that really works for different body shapes and sizes. If, like me, you often feel frustrated that you can't find a bikini top to fit as well as your favourite bra, this bikini top is for you. It has full coverage cups with a subtle underwire that is (genuinely) comfortable – not an easy thing to find, I know. I wore it on holiday with these bikini bottoms but there are lots of matching styles to choose from.

Dipped front | Minimal back coverage | Sizes XXS - 4X

I was a bit worried these would be too small for me but, actually, the high leg made them really flattering. There isn't much coverage on the back, so you may one to go for one of the other matching styles of bottoms if you prefer fuller briefs.

Low scooped back | High leg cut | Designed to fit XSmall-XXLarge | Machine washable

Best square neck one piece swimsuit for bigger busts

Hannah Banks-Walker, head of fashion commerce, says: I have to admit I was skeptical about Hunza G's one-size-fits-all approach but, having tried on this swimsuit, I'm a total convert. I never thought I could wear square necklines because of my boobs but this one really is flattering and makes me feel fab. It has a low scooped back and high leg cut, which I had previously stayed away from but which, in the hands of Hunza G, is not as scary as it sounds. I have and would recommend this swimsuit to anyone who will listen. It's certainly worth the investment.'

Lightly padded cups | Designed for sizes 6-20 | Underbust panelling | Supportive straps

Best tankini for bigger busts

Available in sizes 6-20, I can confirm that this tankini is great if you have bigger boobs and want swimwear with more coverage. It has lightly padded cups to offer extra support and is made of a lovely material that even boasts SPF protection. You do still need suncream, though, so please don't skip that step at the pool.

Designed for sizes 6-20 | Machine washable

These bottoms have what I would call a traditional bikini bottom fit, so they offer pretty good coverage and sit on the hips. I really liked them with the tankini top, because I didn't feel too covered up but still felt supported and confident.

Underwire support | Adjustable straps | Open back detail | Designed for sizes 2-20

Best underwired one piece swimsuit for bigger busts

Hitanshi Kamdar, Grazia's senior commercial content writer says: 'As someone who's size 16 with fairly large boobs, finding the right swimwear is hardly ever easy. So when I tried on Monday Swimwear's crinkled one-piece and it fit perfectly, I was surprisingly impressed. The underwire means there's plenty of bust support, while the sturdy straps keep the cups in place to reduce the risk of overexposure while you're actually swimming. Plus, the crinkled fabric is incredibly flattering, which is always great for a confidence boost at the beach when I'm usually feeling self-conscious. Its simple silhouette also means that it'll look good with some jorts for a relaxed day in a coastal town.'

Padded cups Wide straps which are flattering Gives great support

Best triangle bikini for bigger busts

Available in pink and navy, this top offers brilliant support for sizes 32D-38E. It has supportive straps but they're not overly wide, so felt more flattering than some of the bikinis I've tried with super-wide straps. If you want to buy the set, you can choose classic bikini briefs or the high waisted style for extra coverage.

Full coverage | Comfortable | Available in pink or navy to match the top

These high-waisted briefs are super-flattering and feel really supportive, much like the matching top.

SKIMS

Among the best swimwear for big boobs has got to be Skims, which is legendary for being as size inclusive as it is statement-making. This Scoop-Neck One Piece is very Baywatch - and comes in XXS-4X. If you haven't shopped the brand before and don't know which to take, refer to its size guide which breaks down each by measurement for ease. I wore this on a water slide and still felt fully supported and confident – it's one of the best swimsuits I've tried, which is probably why it sells out very quickly.

Best printed bikini for bigger busts

TONA, founded by style director Tona Stell, has developed something of a cult following since launching in 2021. Its sustainable bikinis are specifically designed for larger cup sizes, ranging from 32DD to 38G, with under-wiring, a double lining and adjustable straps for maximum support. This is, without doubt, one of my favourite brands for swimwear. I've worn this particular bikini countless times and won't be parting with it any time soon.

Fully lined | Medium coverage | High leg cut

With their high waist and high leg, these bottoms are a contemporary spin on a retro silhouette which I always find incredibly flattering.

Best Swimwear For Bigger Bust FAQs

How do I choose swimwear for my body type?

You want your swimwear to highlight your best features and make you feel great - right? The key is to know your body and what works best with your shape. If you have a bigger bust, there are plenty of swimsuits and bikinis that have features like built-in bras and adjustable straps. Darker colours, prints and one-pieces will always be the most flattering. Those with a smaller bust might prefer to elongate their figure with vertical stripes, high-cut legs and plunging necklines.
Individuals with a hourglass shape might gravitate towards swimwear that highlights your waist with more classic cuts like high-waisted bottoms and halter necks.
For a more pear-shaped person, you're going to want all the embellishments. Think ruffles and bold prints, and match them with a sleeker pair of bottoms.
Anyone with an apple shape can create a balanced silhouette by simply pairing underwire tops with high-waisted bottoms, or with anything with ruching.
