Size Range: XXS–3X | Materials: CiCLO natural fibers | Colors: 4 The Best Plus Size Swimwear of 2024, According to Editors and Reviews What to Know About Plus-Size Underwear Size As stylist Ashley Full puts it, underwear is the starting point to every outfit. And when it comes to shopping for plus-size underwear, size is crucial. Full explains that many brands are still learning what a true plus-size scale is, resulting in products that often run small. To avoid any sizing mishaps, she suggests looking for brands that showcase their underwear designs on different body types. “This will give you a better idea of how the item will fit, and having a plus-size model is a good indicator that the brand used a plus-size woman to fit test their designs,” Full says. "Not all brands do this, and it makes a huge difference when it comes to accurate sizing.” Support Finding the right amount of support in underwear can be tricky, but it is possible. Make sure you're getting the right amount of support by choosing undies with all the right features (elastic waistband and leg openings, comfortable fabric, etc.) before you hit buy. “It’s kind of like the tale of Goldilocks and the Three Bears,” Full explains. “You’ll want something that is not too stretchy and not too tight, but just right.” Quality “Finding plus-size lingerie you love isn’t easy, so a high-quality piece is often worth spending a little extra on,” Full tells PEOPLE. “These pieces are usually built to last, and the more you can use it, the more value you get.” Materials When it comes to underwear materials, the options are truly endless: silk, mesh, cotton, and more. But no matter what material you choose, the most important question to ask yourself is how it makes you feel, says Full. After all, you're going to be wearing underwear all day long, so it should feel like a second skin. If you want a pair that's breathable, look for underwear made with cotton or other natural fabrics like bamboo. Underwear made from synthetic materials tends to be less breathable than underwear made with cotton, silk, or bamboo fabrics. Our best cotton underwear pick, for example, is the Duluth Trading Co. Plus Free Range Organic Cotton Hi-Cut which features 94 percent organic cotton with 6 percent spandex to achieve the product's four-way stretch and soft-on-skin benefits. Frequently Asked Questions How do you measure for plus-size underwear? When it comes to plus-size underwear, it's all about knowing your measurements, says Full. “Figure out your chest (for bras), waist, and hip measurements to help you determine how the designer scaled when designing their underwear,” she explains. “With plus-size, this is crucial, as XXL is not equivalent to a 2X.” Is it better to buy underwear bigger or smaller? Because plus-size underwear options are still evolving, you may find pairs from some brands run small, explains Full. “So, if you're having trouble finding the correct size, or are between sizes, don’t feel discouraged to size up for a more comfortable fit." What material are best for underwear? “Whether you are plus-size or straight size, material preference is always subjective,” Full tells PEOPLE. “Numerous people encounter sensory difficulties with specific fabrics or struggle with tight waistbands, so you really need to find what works best for you. With that being said, I recommend choosing underwear made from natural fibers like cotton. Cotton is breathable, comfortable, and cooling, making it a great go-to fabric choice for all body types.” Why Trust PEOPLE? Courtney Leiva is a contributing commerce writer for PEOPLE and has also written for publications including InStyle and Martha Stewart Living. For this story, Courtney interviewed plus-size stylist Ashley Full on what features to look for in plus-size underwear and how to find the best fit.
