The 8 Best Plus-Size Swimwear of 2025, Reviewed

Finding cute, comfortable swimwear that will last more than a season or two can be difficult. If you’re plus size, the search can be even more difficult, as many brands don’t make a wide enough size range or consider how the designs translate from small to large frames. Even though the market has changed for the better in terms of size inclusivity, the selection of plus-size clothing isn’t as extensive as it could be.

Yes, there are cute, trendy options, but finding them requires a little more hunting. As Cameron Armstrong, co-founder of size-inclusive swimwear brand Kitty + Vibe, says, there are some tips and tricks to make the process easier. “When shopping for plus-size swimsuits online, look for product pages that showcase plus-size models wearing the swimsuit,” she explains. “You should see your size proudly represented and be able to trust that the brand took care in fittings for plus sizes as well as straight sizes.” If you’re looking to start your search, keep scrolling. We researched the available options, tried a few for ourselves, and spoke with several experts to ensure we’re recommending the best of the best. Ahead, find a list of the best plus-size swimsuits.

What to Look for in Plus-Size Swimwear

• Fabric: Searching for the right fabric for swimwear can be tricky. For starters, Katie Murphy, the Head of Fashion for 11 Honoré at Dia & Co., highlights a few key features to look for. “They must be quick-drying, colorfast, and have a certain amount of elastane, or stretch,” she says. “Fabric is meant to stretch to fit all those gorgeous curves and for us to be comfortable. It also needs to be able to both hold its shape when wet and to dry easily and quickly.” No matter the swimwear brand, you’ll often find most suits made from polyester or a polyester blend because it’s one of the few fabrics that’s able to maintain its color while being able to withstand chlorine without shrinking and fading. (It also happens to be the most long-lasting and durable.) Polyester can protect your skin from UV. However, cotton, spandex, nylon, and LYCRA® are also popular options for their qualities of softness (cotton), stretchiness (spandex), and quick-drying (LYCRA®).
• Construction and Fit: “When shopping for plus-size swimwear, you should look for product features that provide the proper level of support,” Armstrong says. “Some swimsuit brands include an extra layer of power mesh in between the liner and the swim fabric so the material isn’t overstretched when the breasts are heavier.”
• Design: Every plus-size body is different, so what works for one body type may not work for yours. Whether it’s a bikini or a one-piece swimsuit, it’s important to prioritize the fits and silhouettes that will make you feel best in your body. “Crowd pleasers in swimwear are one-shoulder tops or one-pieces,” says Murphy. “These work for large and small busted bodies as well as accommodate different shapes on the bottom.” But what’s most important to her is to “embrace the curves and wear what you feel best in.”

FAQ

• “To preserve the vibrancy of the colors in your swimsuit, as well as ensure the fit isn’t warped, we always recommend hand-washing your swimsuit in cold water and laying it flat to dry,” Armstrong says.

  However, Murphy says you can machine wash, too. “Ideally, hand-wash after every wear,” she says. “But realistically, most of us machine wash, so do so with cool water and a mild detergent and lay flat to dry.”
