The 13 Best Plus-Size One-Pieces, Bikinis, and More for Summer 2024 (2024)

Finding swimwear that’s cute, comfortable, and feels like something that will last you more than a season or two can be difficult. If you’re a 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 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 for somewhere to start your search, just keep scrolling. We researched the options available, 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 on the market right now.

What to Look for in Plus-Size Swimwear

Fabric

Searching for the right fabric for swimwear can be tricky. For starters, Murphy 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 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 is able to protect your skin against 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.”
