Best for Tummy Control: Miraclesuit Plus Size Moderate Control Hi-Waist Brief

This full-coverage shaping brief from Miraclesuit is a winner in more ways than one.

The Wonderful Panel Tummy also provides excellent tummy control and shaping — all while remaining invisible under your clothes (kind of like magic).

While this brief offers the ultimate shaping experience, there are some caveats. It is only available in two colors, and because it holds everything in, it has a fit some may find too tight or restricting.

We totally get it: Shapewear might not be the most glamorous thing to wear, but don’t let that fool you into thinking it’s uncomfortable. With a high-quality piece like this, you'll be amazed at how many years (and uses) you’ll get out of it.

Best Shapewear: Shapermint High Waist Shaper Briefs

But they aren’t only smoothing; they're also sturdy with a non-slip grip, and a double-layered design offers great coverage from top to bottom. Of course, the five classic colors are the cherry on the top of the sundae.

However, you’ll want to remember that shapewear is like a push-up bra for your whole body — it can work wonders, but it's not always the most comfortable option. If comfort is a priority, we recommend going with the tag-free and breathable Fruit of the Loom Women's Eversoft Cotton Brief which comes in a pack of six.

Best Sustainable: Uwila Warrior Better Briefs

If you're looking for a comfortable, everyday pair of underwear, consider the Better Briefs from Uwila Warrior. Apart from the sustainable materials, the underwear provides full coverage with its classic silhouette. Plus, the undies come in a wider range of sizes from XXS to 3X and are available in three neutral colors. And while they're a little more expensive than some underwear on our list, with Earth Day coming up, we think it's great to invest in the planet while building your wardrobe.

How to Pick the Right Plus Size Underwear


As plus size 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.”


Finding the right amount of support in underwear can be tricky, but it is possible. Just 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.”


“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.”


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're wanting a pair that's breathable, however, look 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 fabricsw. 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.”
