Models wearing the best bodysuits

Byrdie / Alli Waataja

Bodysuits are the ultimate fashion solution. They stay tucked into your pants or skirt while smoothing your midsection and cinching your waist, and they can be layered under anything from oversized button-ups and blazers to bombers and leather jackets

Yet the design can offer its own set of pitfalls like riding up, lack of adjustability, and complicated bathroom breaks. So we tested 28 of the most popular bodysuits on the market to see which ones are worth the hype. We gave each bodysuit to two testers with different body types. Over the course of two weeks, the testers wore the bodysuits to work and social events and made notes of the fit, comfort, durability, materials, and style. Here are the best bodysuits we don’t mind shimming into.

Fabric: Polyamide, elastane | Sizes: XXS–4X | Colors: 14 | Bottom: Thong

If you're looking for an all-around excellent bodysuit, Skims won't let you down. This bestseller features a subtle square neckline, narrow (but not too thin) straps, a low scoop back, high-cut leg openings, and thong coverage that promises to disappear under pants and skirts. As part of the brand's fan-favorite Fits Everybody line, the buttery-soft, incredibly stretchy fabric expands to four times its original size—so not only will it fit every body, but it'll always fit. When we first took it out of the packaging, we thought it looked a little small, but the fabric beautifully sculpted our body, leaving us confident and comfortable. Not too thin yet not too thick, the fabric supported our chest even without a bra. And it’s durable too, with no ripping, pilling, or shrinking after wearing or washing.

Fabric: Cotton, modal, spandex | Sizes: XXS–XXXL, tall | Colors: Black, white | Bottom: Brief

Nothing can replace the versatility of a good white T-shirt, but if you are tired of having to constantly tuck it back into your jeans, check out this bodysuit from Gap. It gives you the look of a classic crew neck with a full coverage, snap gusset bottom. While we often feel like our body has to conform to the shape of the bodysuit, we loved how this cotton modal blend followed the curves of our body for a comfortable, unrestrictive fit. Despite being buttery soft, the fabric didn’t succumb to regular wearing or washing. And it’s not see-through, even in the white version. You can’t beat the price and the versatility to dress it up or down.

Fabric: Cotton, polyamide, elastane | Sizes: XS–L | Colors: 9 | Bottom: Brief

Yes, we know, spending nearly $300 is A LOT for a bodysuit, but what if we told you this is one of the best ones we’ve tried? When we first took the product out of the packaging, we were worried the thick, opaque material might be uncomfortable, but it completely shocked us by being unbelievably soft, stretchy, and breathable. We could stretch, dance, and move our body as if we were naked, totally unrestricted. To add to the sleekness, the suit has a subtle sheen that can be seen in all nine colors while featuring soft cotton fabric on the inside. While this suit doesn’t sculpt as much as the Skims Bodysuit, it did offer enough support and coverage to ditch the bra. The price isn’t for everyone, but if you’re serious about investing in a bodysuit that you can wear for years, give it a try.

Fabric: Recycled plastic bottles, spandex | Sizes: XXS–6XL | Colors: 5 | Bottom: Brief or Thong

We’re all for inclusivity and sustainability, and this bodysuit checks both of those things off the list. Like most of the brand’s collection, it runs from XXS to 6XL and is mainly made from plastic water bottles. On top of that, it gives you options by coming in both a brief and thong bottom. We appreciated the added shelf bra on this square neck design, though we found those with large breasts still need more support. The fabric was soft and stretchy, with no seams or closures to dig into the skin. It’s worth noting that there aren’t buttons on the bottom, so going to the bathroom is a bit tricky. And if you have a long torso, you might want to size up.

Fabric: Rayon, spandex | Sizes: XS–XXL | Colors: 25 | Bottom: Brief

Amazon is our go-to for affordable style staples and this bodysuit is the perfect example. It’s on the lower price spectrum yet still offers exceptional durability and fit. It was the ideal size for both of our testers, despite one having a longer torso, which can make bodysuit shopping so much harder. While the material is not as thick or compressive as some of the others on this list, the thin, breathable quality makes it a great pick for everyday casual wear. Think of it like your favorite long sleeve shirt but better.

Fabric: Nylon, spandex | Sizes: XS–XL | Colors: 4 | Bottom: Thong

A long-sleeve bodysuit is a great layering piece, especially when it comes in neutral colors like this one. We loved the suit’s “second skin” fabric, which was not too thin or thick and had the right amount of stretch and comfort without losing its shape. We were also impressed with the button closures at the bottom that were easy to clasp and comfortable. Our only complaint is that our bra was visible under the material, yet we didn’t feel comfortable going without one.

Fabric: Nylon, spandex | Sizes: XS–XXXL | Colors: 11 | Bottom: Thong

Thanks to the thick straps, this bodysuit lets you wear a “normal” bra, thus crowning it as our favorite tank style. Add in the deep scoop in the front and back, and you have a subtly sexy top. Yet what really sold us on this bodysuit was the double-lined material. It felt luxurious and tastefully cinched our postpartum stomach without feeling like a corset. Plus, it is opaque enough that we could wear a dark bra under a light shade without it peeking through. Our 5-foot-5-inch tester said the suit felt true to size, while the 5-foot-9-inch tester said it was a bit short in the torso, so consider sizing up if you are tall or have a long torso.

Fabric: Polyester, elastane, cotton | Sizes: XS–3X | Colors: 2 | Bottom: Thong

Calling all those who want a turtleneck without the bulk, this one's for you. This bodysuit is one of the softest pieces of clothing we own, yet it’s also breathable and warm. The material is opaque and stretchy, leaving us unrestricted every time we wear it. And the fabric still looked great after wearing and washing. Though it doesn’t have the degree of compression as the rest of the brand’s shapewear, it did cinch our waist and boosted our confidence. We recommend sizing up for the best fit.

Fabric: Nylon, spandex, cotton | Sizes: S–4XL | Colors: 8 | Bottom: Brief

Consider this your favorite shapewear bodysuit, except you can wear it on its own, instead of only under clothes. With medium compression, this suit smooths your stomach, butt, and upper back. We did feel the compression but it wasn’t too uncomfortable or restrictive. And the compression level held up after wearing and washing. Unlike other bodysuits, this one comes with adjustable straps as well as a wide three button gusset, which prevents riding up—though it can be harder to close.

Fabric: Nylon, elastane, cotton | Sizes: One Size | Colors: Black | Bottom: Thong

There’s something so effortlessly chic about an off-the-shoulder top. Yet if you’ve been scarred by constantly having to adjust the neckline, give this bodysuit a try. The neckline didn’t slip, even while dancing. This is likely due to the brand’s seamless microfiber material which molds to the body. And we skipped the strapless bra since the thick construction offered enough coverage and support. We’re a bit skeptical of anything one size fits all, yet the stretchy material fit our 5-foot-10-inch tester to a T. The peace of mind of being able to move around without an outfit malfunction is priceless.

Fabric: Nylon, Lycra Elastane, | Sizes: XXS-1X | Colors: 6 | Bottom: Thong

Whether you like the edges of your bodysuit peeking through or the hourglass silhouette that a high-cut suit creates, this one from Lululemon offers plenty of leg. Just like your favorite leggings, this bodysuit is buttery soft, stretchy, and stays in mint condition despite wearing and washing. It’s not meant for workouts, but we could wear the suit with or without a bra. We overall loved how it looked, even though it offered less sculpting powers than others. Just note that the plastic buttons take some time to finesse.

What to Look for When Buying a Bodysuit

  • Fabric: Overheating, sweating, or feeling too restricted in a bodysuit is never, ever fun. When browsing options, look for fabrics that are not only stretchy but also breathable and moisture-wicking. Many bodysuits feature a primary fiber, such as nylon, cotton, viscose, or rayon, with a small amount of spandex or elastane woven in for flexibility and stretch. If you go for a shaping design, the material might be thicker and more compressive.
  • Size and Fit: Finding the right fit is also crucial. Even when a bodysuit is technically true to size, it'll often feel tighter than a regular shirt since the panties and shoulders pull in opposite directions—similar to a one-piece swimsuit. Check the brand's size guide for insight, and consider how you'll wear the bodysuit, whether as shapewear, an undershirt, or as your main shirt. If you want a gentler, not-too-snug fit, order a size up from what you normally wear.
  • Color: As wardrobe staples that often act as undershirts, bodysuits typically come in nude shades to complement different skin tones. You'll also find other neutrals, like black, white, navy, and gray. There's nothing wrong with a pop of color, but you might get more wear out of a more versatile hue.
FAQ
  • How do you style a bodysuit?

    Bodysuits can be styled many ways—as an undershirt or layering piece under a maxi skirt, sleeveless dress, or cropped jacket. "We can layer them under blazers to elevate them for work or with a pair of jeans and ballet flats for an off-duty model approach," says fashion expert Laura Silvia Gesuito. Stripe & Stare co-founder Katie Lopes loves styling them under sweaters. A bodysuit can be the primary top for an outfit or even worn as shapewear.

  • Do you wear underwear with a bodysuit?

    You can wear underwear with a bodysuit, but you don't have to. According to Lopes, it's about a 50/50 split in terms of wearing panties or "going commando" (if you can call it that) in a bodysuit—at least in her office. The panty portion of most bodysuits features a cotton gusset to provide breathability in the crotch area (like regular underwear), but some may not offer the amount of coverage you want. It really comes down to comfort and personal preference.
