How to shop for swimwear

Just like shopping for plus-size shapewear and plus-size dresses, great plus-size swimsuits are notoriously difficult to find. They require an impeccable fit, quality materials, and gorgeous silhouettes that help the wearer feel her best. Not to mention, the plus-size swimwear that’s comfortable for one person might be a poor match for another. However, we’re here to take the guesswork out of shopping for swimsuits—especially if you’re looking for an extended size.

Ahead, we’ve rounded up the best plus-size swimsuits in every silhouette to make you feel amazing. Whether you’re heading to a beach resort, a poolside cabana, or your very own backyard, these comfortable, feel-good swimsuits will help you sunbathe in style. Now, all that’s left to do is round up your favorite swimsuit cover-ups, sunglasses, sun hats, face sunscreen, beach towels, and beach chairs, so you can prepare to hit the sand.

How we chose the best plus-size swimsuits

To make these recommendations, we found the best plus-size swimwear brands and researched their best-selling and top-rated styles, from tummy-control swimsuits to bikinis. We also looked for a range of details that make a swimsuit great, including a supportive bust, a good cut, UPF protection, and an inclusive size range. Each product recommendation with a star rating has four or more stars. So grab one of your favorite beach reads and get ready to soak up the sun.
