Stylish & Supportive: The Best Underwire Swimsuits

Find the perfect fit with these trend-forward and supportive swimsuits!

Searching for swimwear can be stressful for shoppers with larger busts. Many swim styles like the classic triangle bikini, don’t provide support and run a high risk of accidentally becoming undone at the worst possible moment. Today, there are so many great options with well-constructed designs and fabric made to support you, whether you’re full busted or just in need of a little lift. Whether you’re looking for a bold basic for the beach or pool, or you’re looking for more on-trend swim styles that’ll look chic and provide your boobs some support (and alleviate the potential for boob sweat—every busty woman’s enemy), we’ve got you covered with our list of must-have supportive swimsuits!

Tricks for Finding the Supportive Swimsuit of Your Dreams

Since most of us shop online now for our swimsuits, it’s good to go in with a little bit of knowledge before ordering a bunch of bikinis and swimsuits haphazardly to your door. If you’re in need of breast support from your swimsuit, make sure to order styles that include adjustable straps (preferably not spaghetti straps, but something thicker) and closures to help with lifting your chest. Underwire is also a must for those in need of bust support. There is cup-sized swimwear available, but usually, a one-piece or bikini with underwire, stretch fabrics, and supportive straps are all you need. Additionally, scoop and plunge style necklines for swimsuits are excellent at both supporting bigger busts and flaunting your fabulous figure.

Do Underwire Swimsuits Offer Better Support?

Yes! Underwire swimsuits definitely offer better support, whether you’re plus-sized, big-busted, or just finished breastfeeding. Underwire works by separating the bust from the midsection and therefore creating a more defined silhouette. For this reason, petite women also benefit from swimsuits with underwire as it helps to define and enhance the appearance of the bust. Additionally, underwire bikinis with well-made shoulder straps work together to help balance the weight of your bustline so they don’t pull down on your neck and shoulder. If you plan to have a more active day at the beach, swimming or running, underwire bikinis are sure to stay in place, no matter what.

The Best Underwire Swimwear Styles

Now that you have an idea of what to look for when searching for supportive swimwear, let’s find your dream swimsuit! Whether you're DD+ or just need help fighting gravity, these luxurious and well-constructed styles will inspire you to start planning your next beach vacation ASAP!

Denim is Back!

If you religiously follow the trends and love the current resurgence of all things Y2K, you will be obsessed with this denim-inspired bikini from Karla Colletto. Complete with a supportive underwire, adjustable straps, and an Americana-inspired denim-colored fabric, the Indi Bikini Top expertly walks the line between modern and retro chic. Wear it with airy high-waisted pants post-swim for a boho-chic beach look.

Inspired by innovations in sculpture and architecture, this unique fashion brand always creates silhouette-flattering styles with pieces that are designed to last. This underwire swimsuit is made with lustrous satin fabric for a touch of glamour and features an eye-catching cutout detail under the bust. The shade of this supportive swimsuit is called ‘Mykonos’ and already has me dreaming about a whirlwind trip around the Greek Isles!

We love Kulani Kinis’ Ditzy Underwire Bikini Top in bubblegum pink for a fresh take on the still popular Barbiecore trend. This textured ribbed pink bikini top is unpadded with underwire cups and adjustable shoulder straps.

Eye-Catching Prints

It’s no surprise that Brazilian Swimwear brand, Farm Rio, knows how to make fabulous styles and their Underwire Bikini Top is no exception! If you prefer your prints and patterns to be more graphic and statement-making, the black and white palm tree print of this swimsuit is for you. We love the contrasting combination of stripes and palm trees that can be seen from across the beach. This supportive swimsuit includes cups with underwire, hook and eye closures, and stylish (but sturdy) straps. The matching high-waisted bikini bottoms for this bikini style are also reversible, so you can choose from the palm print or stripes. Wear this swimsuit on days when you’re looking to embody the fun and carefree spirit of Brazil.

Underwire Bras for Small Busts

As we noted earlier, women with smaller boobs can also benefit from swimsuits with underwire! If you’re looking to add a little more oomph to your cleavage area without sacrificing sophistication, you need Farm Rio’s Floral Underwire Bikini Top. This lilac and yellow floral printed bikini includes cups with underwire for support and a ruffle on top of the cup to add a sense of fullness to your bustline.

This lavender underwire bikini top includes spaghetti straps that cross and tie at the neck, a hook-and-loop clasp, and individual underwire cups.
