So today we’ll talk about that. Plus size one-piece swimsuits aren’t the boring options that cover everything like they used to be. Dresses are totally having a fashion moment, and the plus size market is offering styles that are bold, sexy, and absolutely worth showing off.
We’re talking cutouts in all the right places, plunging necklines, metallic finishes, animal prints, ruffled one-shoulders, and high-leg silhouettes that make a statement without making a statement. The days when One Piece was a “safe” choice are officially over.
Since it’s #TCFSwim Week, we’ve rounded up some of our favorite plus size one-piece swimsuits in a variety of styles, sizes, and price points. Because everyone deserves to find a swimsuit that makes them feel like they own the pool deck.
Whether you’re by the pool, at the beach, or by the lake, you deserve a swimsuit that makes you feel like the hero. Are you ready? Let’s get started!

What makes a great plus size one-piece swimsuit?
Beyond style, there are some things to keep in mind and specific tips when shopping for the right plus size one-piece swimsuit for you.
Look for a good lining. A well-lined suit will keep everything in place and prevent it from being see-through when wet. This is especially important for bright colors.
Check the fabric content. Suits with a high blend of nylon or polyester and elastane hold their shape better, dry faster, and last longer, especially if you swim regularly.
Consider your activity level. If you’re actually going to be swimming or playing in the waves, look for suits with secure straps, racerback options, or snap closures. If you only stay by the pool, you have a lot more freedom to prioritize style.
If in doubt, size up. Plus size one-piece swimsuits that are too close to your torso are uncomfortable and unflattering. If you’re in between sizes, always size up. Wearing a suit that fits comfortably allows you to actually enjoy your day.
Know your size range. Please be sure to check each brand’s size chart before purchasing. Sizes vary widely from brand to brand, so a size chart is your go-to when shopping online.

Which plus size dress calls your name?
Whether you’re drawn to metallics, bold prints, cutouts, or classic black, the best plus size one-piece swimsuit is one that makes you feel confident, comfortable, perfectly poised, and like yourself.
