Best Bikinis For Large Busts: A Guide to Perfect Support & Style!

Finding the perfect bikini for a fuller bust comes down to feeling supported, comfortable, and confident. You want something that lifts and flatters while still being easy to wear - so you can focus on enjoying your day at the beach or in the water, not spend it adjusting your swimwear. If you’ve struggled to find a bikini that offers enough support without compromising on style, you're not alone.

Did you know that over 81% of women wear the wrong bra size? Just like wearing the wrong bra, wearing a bikini that isn’t properly structured for a fuller bust can lead to discomfort, lack of support, and an unflattering fit. That’s why choosing a bikini designed with lingerie-style support can make a world of difference. And we have some stunning options for you to choose from.

KEY FEATURES TO LOOK FOR IN BIKINIS FOR BIG BUSTS

UNDERWIRED SUPPORT - JUST LIKE YOUR BRA
For a fuller bust, underwired bikini tops are a life saver. Just like your favourite bra, they provide lift, shape, and all-day support, so you can feel secure without constantly adjusting. Choosing a bikini sized by cup and band ensures a snug, stay-put fit. Our DD+ Bikini Tops are designed with this in mind, giving you the same structured support as your go-to lingerie, but made for the beach.

WIDER STRAPS FOR EXTRA COMFORT
Thin straps are cute and dainty but for ladies with a bigger bust, they can dig in and cause discomfort. If you want extra support and all-day comfort, wider straps are the way to go. They help distribute weight more evenly, taking pressure off your shoulders while keeping everything secure.

HIGHER COVERAGE & LONG-LINE STYLES FOR SECURITY
If you prefer a little extra coverage, long-line bikini tops and high-cut styles offer more than just added support - they create a smooth, sculpted silhouette that feels as good as it looks. Designed to prevent spillage and provide a secure fit, our DD+ swimwear range offers supportive options that move with you.

BEST BIKINI STYLES FOR A LARGE BUST
Balconette bikinis
A great choice for larger busts, balconette bikinis offer the perfect mix of structure, support, and a feminine, flattering shape. With underwired cups for lift and wider-set straps for a naturally defined silhouette, they keep everything secure while still feeling stylish.

For a stunning and supportive option, try the Amalfi Crinkle Balconette Bikini Top. The adjustable ruching and wide strap details highlight your shape beautifully while ensuring a secure fit. Pair it with the Amalfi Crinkle High-Waisted Bikini Bottoms for a sculpted look that defines your waist and elongates your legs.

Plunge bikinis
If you love a flattering, curve-enhancing fit with just the right amount of support, a plunge bikini is a must. The deep neckline and structured underwire provide lift without feeling restrictive, giving you a secure yet effortless look.

Plunge bikinis are especially great for bigger busts, as they offer support without overly compressing the chest. The Ibiza Crinkle Plunge Bikini Top (available up to a G cup) is designed with this in mind. It offers strong support while highlighting your curves, making it the perfect blend of sexy and secure. Complete the look with the Ibiza Crinkle Bikini Bottoms for a coordinated, confidence-boosting set.

Bandeau bikinis

Can a bandeau be worn with a large bust? Yes! Contrary to popular belief, bandeau bikinis can work for larger busts - as long as they have the right structure. The key to making bandeau styles work is choosing one with an underwire, strong side boning, and a secure band to keep everything in place.

With padded cups, a wired structure, boning for extra support, and a removable halter neck strap for added security the Honolulu Strapless Crinkle Bikini Top is great for fuller busts. Not only does it offer a secure and comfortable fit, but the removable neck strap allows you to wear it in multiple ways. Pair it with the Honolulu Crinkle Bikini Bottoms for a chic and comfortable set that’s perfect for lounging or swimming.

THE BEST COLOURS & PATTERNS FOR A FULLER BUST
The right colours and patterns can make all the difference in swimwear, helping to balance your shape and highlight your best features. Whether you’re into classic, understated styles or bold, eye-catching designs, a few small design choices can make a big impact.

- DARK, SOLID COLOURS: Deep, rich tones provide a streamlined effect, helping to downplay volume for a refined, sophisticated silhouette.
- VERTICAL STRIPES & STRUCTURED SEAMS: These details help elongate your frame, offering a balanced and proportionate look. Clean, structured lines add subtle definition and shape.
- BOLD PRINTS & COLOUR-BLOCKING: Vibrant patterns and contrast panels naturally draw the eye, letting you highlight the areas you love most while creating visual interest.

If you want to balance your shape, try a darker bikini top with a patterned or lighter bottom to draw the eye downward. If you love showing off your curves, go for bold prints or bright colours up top for a confident, statement-making look.
