6 Best Shapewear to Wear Under Wedding Guest Dresses

Finding the best shapewear for a wedding-guest dress often comes down to the outfit itself. After all, a strapless neckline calls for a different solution than a plunging halter, while a slinky slip dress may require more smoothing than a fit-and-flare dress. Maybe you’re looking to prevent thigh chafing, create a more snatched silhouette, or simply want a little tummy control during hours of celebrating and dancing. Whatever your goals, we’ve rounded up the most versatile, comfortable shapewear for every wedding on your summer calendar—all of which we’ve tested ourselves.

Spanx

What we love: This silky Spanx shapewear bodysuit gives you smoothing and support without sacrificing a plunging neckline. “I rarely wear low necklines because sticky bras never stay put, but this low-back, mid-thigh bodysuit worked perfectly under my plunging halter dress,” says Glamour contributor Dory Zayas. She praised the U-shaped front for staying hidden under deeper necklines. Another tester was impressed by the soft fabric and silicone grippers, which helped prevent rolling under form-fitting dresses. Medium compression smooths the waist, hips, and thighs, while a pull-aside gusset simplifies bathroom breaks.

Honeylove SuperPower Shorts

$89

Nordstrom

What we love: For body-skimming dresses, these muhteşem high-waisted Honeylove shaper shorts are a longtime favorite of Glamour testers (and are one of our top picks for plus-size shapewear). Crisscross compression panels create an hourglass effect, while side boning and a silicone-lined waistband help prevent rolling. Convertible straps allow you to wear them as an open-bust bodysuit for extra security. Glamour contributor Maggie Griswold (who wears the shorts in a 2X) was impressed with the smooth look they created under a slip dress and slip skirt. “The fabric around my thighs, which hits a few inches above my knees, didn’t move or roll at all and helped minimize chafing,” she says. “They hit right at my waist and felt supportive and contouring through my midsection.”

Skims Seamless Sculpt High Waist Thong

$34

Nordstrom

$36

Skims

What we love: This Skims tummy-control underwear is a good middle ground for slip dresses, fit-and-flare styles, and other looks that need a little smoothing through the stomach without the extra coverage of a bodysuit or shorts. “This ultra-high-waisted thong is soft, stretchy, and flexible—great for days where lots of movement,” says Glamour commerce writer Alanna Martine Kilkeary. The seamless thong design stays discreet under clothing, and the size range extends up to 4X.

Shapermint Essentials Open Bust Bodysuit Shaper Panty

$29 (40% off)

Shapermint

What we love: With open-bust shapewear, you get the smoothing benefits of a bodysuit without being locked into its built-in bra—a major advantage since fixed cups often gape on smaller busts or fail to provide enough support for larger busts. This Shapermint bodysuit offers strong compression through the stomach and hips while letting you pair it with whatever works best for your dress, whether that’s your favorite bra, nipple covers, or nothing at all. Glamour contributor Brigitt Earley, who tested a similar scoop-neck style from the brand, praised the soft fabric and comfortable fit. Adjustable straps, breathable mesh side panels, butt-lifting brief cut, and a snap gusset make it especially practical for long events.

Shapellx Bare Essentials AirSlim Hourglass Full Body Brief Bodysuit

$68

Shapellx

What we love: If you’re looking for a true body shaper, this Shapellx bodysuit delivers some of the strongest contouring of any we tested. It has a noticeably cinched effect while smoothing through the stomach, waist, and hips. “The hook-and-eye fasteners up the chest with a zipper on top really sculpt your waist—I’ve never had an hourglass silhouette like this before,” says Glamour commerce editor Malia Griggs, who wore it under a high-neck fit-and-flare dress. “It gave my booty some lift, too (nice).” A built-in bra and boyshort cut softened by lace trim provide full coverage. For a strapless shaper, we like Skims’s Body Core Sculpt Waist Cincher corset.

What we love: When your ball gown bares your shoulders, a good strapless bra is a must. We’ve tested plenty of styles over the years, and this one from Spanx remains a favorite. “The wings have more silicone strips than any other bra I tried, and silicone dots along the cups keep it from slipping or gaping,” says Earley, who wore it through a full day of walking and hours of dancing with only minor adjustments. The smooth, breathable fabric lies flat under clothing and creates a natural shape without visible lines, making it a smart option for strapless, off-the-shoulder, and sweetheart-neckline dresses. (For a strapless, backless dress, you’ll need a different solution entirely, like a sticky bra, nipple cover, or boob tape—our favorite for special occasions is Gatherall’s reusable adhesive bra.)
