The 17 Best Strapless Bras, Tested & Editor-Approved

Whether you're wearing an off-the-shoulder gown or a backless number, there's a high chance you'll need a strapless bra on your wedding day. But finding one that doesn't pinch your skin or, worse, slide down can be challenging. Luckily, reliable (and stylish) options exist, and the right bra can reduce your wedding day anxiety.

"Some of the key elements you should look for when shopping for a strapless bra are the right cup size, multiway straps, a no-slip grip, and comfortable boning on the sides," says Ra'el Cohen, the co-founder and COO of ThirdLove.

We tested different styles of strapless bras across cup sizes over two weeks. We wore the bras for several hours to replicate wearing them at a wedding, plus we added some dancing and jumping for good measure. We also measured the band to see if it stretched after washing and wear. With all these insights, we compiled our list of the best strapless bras for every cup size, dress style, and skin tone.

Say goodbye to pesky bras that pinch, squeeze, and slip. Spanx has designed the ultimate strapless bra that won't let you down—literally. Even while wearing this bra for a full day, we didn't find ourselves having to adjust it or lift it up, as we often do with other strapless bras.

We measured carefully, and after two weeks of wearing and washing the bra, we found no stretch in the band. Even with the SmartGrip technology that holds it in place, the bra felt comfortable enough to wear daily. We also loved how there were no tags or elastics, which ensured a seamless look and feel.

Size Range: 32A–40DD | Material: Nylon, elastane | Padding: Yes | Colors: Black, beige

For a strapless bra that can easily be worn under both your wedding dress and your favorite white tee, opt for this lightly lined style from Aerie. Removable straps give you the freedom to wear this versatile bra with a number of outfit choices, from your bridal shower to the rehearsal dinner and beyond.

This was one of the most comfortable, well-fitting strapless bras we tried, even for those of us with large chests. We wore this bra out dancing, and the moisture-wicking fabric kept us dry while our girls felt supported and the band stayed in place. Plus, it comes in five shades to match a range of skin tones.

Size Range: 32A–40D | Material: Recycled nylon, spandex | Padding: Yes | Colors: Black, brown, tawny, beige

Aptly named the "Stay Put" bra, this affordable style didn't slide down and required little adjustment while we wore it for eight-hour days. It offers full coverage while still being low enough to wear with low-cut tops. We also loved how seamless the overall design looked under our clothes.

The bra does come with a decent amount of padding, which those of us with smaller chests appreciated. If you'd rather go without the padding, consider Natori Feathers Strapless Bra.

Size Range: 34A–40DD | Material: Nylon, spandex | Padding: Yes | Colors: Black, beige, white

There's no denying that a strapless bra is an essential undergarment to have in your bridal wardrobe. So why not invest in a high-quality one that'll last for years? The lace band makes this Cosabella style surprisingly elegant for a strapless bra, though it feels more delicate due to the material. Still, the band didn't stretch after two weeks of wear.

We loved how the silicone strips and side boning ensured the bra didn't move at all, yet both features were comfortable and nonirritating. With a plunging front and convertible straps, you can wear it with nearly any dress. Best of all, the straps weren't flimsy and never unlatched by themselves.

Size Range: 30C–36F | Material: Polyamide, elastane | Padding: Yes | Colors: Black, beige, red

"A comfortable strapless bra that stays up is key, and this one will exceed your expectations," says Cohen. "It's made with soft-support foam that's outfitted with a smooth band and silicone along the edges to stay in place without digging in." The silicone strips did take some getting used to, but they certainly did their job.

We wore this bra to a pottery class (which, if you don't know, involves hunching over your work), and it stayed in place and was surprisingly comfortable. The smooth microfiber held up well, even after washing, and no tags meant no itching. The bra blended seamlessly under our clothes, though if you're wearing a low-cut dress, you might want to go with a plunging design, like the Cosabella Plungie Bra.

Size Range: 32A–44E | Material: Nylon, spandex | Padding: Yes | Colors: Black, taupe

If you have a smaller chest and can't seem to find a strapless bra in your size, check out this style from Pepper. Specializing in smaller cup sizes, Pepper has crafted the ideal strapless bra for AA, A, and B cups—no gaping or slipping involved.

The design features a thicker band, which limited our outfit choices. Still, we appreciated how it ensured the bra stayed in place. With underwires and lightly lined cups, this style is ideal for those who don't want bulky padding. If you want more lift, consider Maidenform's Stay Put Bra, which was a favorite among us with smaller chests.

Size Range: 30A–40A | Material: Polyester, elastane | Padding: No | Colors: Ecru, sand, blush, beige, camel, brown, black

If you're worried a strapless bra will create an unflattering uni-boob, this one from Curvy Kate has you covered. Specifically made for sizes D and up, the design featured underwire cups that lifted and separated our breasts.

We definitely noticed the support, as it reminded us of wearing a corset. But the snug fit kept the wide band in place, even as we raised our arms overhead or bent over, so it's dance floor-ready. We also liked how the cups provided ample coverage, so we didn't feel like our nipples were about to pop out. The light padding and side boning didn't bother us, either.

Size Range: 28D–40J | Material: Nylon, polyester, elastane | Padding: Yes | Colors: Ivory, caramel, black, beige

A wireless strapless bra may sound like an oxymoron, but Soma proves it does exist. Thanks to contoured cups, it gives your chest a natural lifted shape. The inside of the bra had a sticky texture—similar to adhesive bras—that provided extra grip without being painful or irritating our skin. In fact, we found it comfortable enough to wear daily, which doesn't happen with strapless bras often.

Plus, the smooth, seamless design complimented all kinds of clothing. We wore it under a bridesmaid dress, and it looked amazing in the wedding photos. With how much we loved the look, we'll even wear it with the detachable straps when we need a racerback or halter bra.

Size Range: 32A–42G | Material: Nylon, spandex | Padding: Yes | Colors: Off-white, sand, beige, sienna, pink, black

For low-cut dresses, like those with plunging sweetheart necklines or cowl-neck slips, we recommend this style from Natori. It's a strapless version of the brand's popular Feathers Bra, which, as the name suggests, is known for being lightweight and streamlined with barely there padding. Even in the strapless version, we found this bra impressively comfortable, as neither the wire nor the lace band dug into our skin.

While the texture of lace can often be detectable under clothes, this one stayed invisible. Though the bra is low-cut, the cups still kept our girls supported and secure, and there was no gaping. We did notice the band wasn't as wide as others on this list, so that might be a deal-breaker for those needing that extra hold.

Size Range: 32B–36DDD | Material: Nylon, lyrca, polyester | Padding: No | Colors: Beige, black

With a wide, four-hook band, this bra smooths and supports to create an incredible lift. We found it a bit tight, but for those of us with larger chests, the extra grip kept us in place for hours on end.

The cushioned band enhances comfort and ensures no marks are left on your skin. The design also offers enough space between the cups to prevent the dreaded look of a uni-boob. Having owned three of these bras in the past, we can assure you it's worth the investment.

Size Range: 30B–40I | Material: Nylon, spandex | Padding: No | Colors: Black, taupe, beige

If you're looking for a sexy strapless bra for your honeymoon rather than a sturdy style to wear down the aisle, we recommend this number from Skims. Made from unlined mesh, it didn't give us too much coverage or support, which, depending on the occasion, could be exactly what you're looking for.

Despite the sheerness of the fabric, we noticed no wear or tear after wearing and washing for two weeks. Finding the right size was a bit tricky—like many Skims pieces, the bra seems to run small, even when following the size guide. But thankfully, you have 30 days to make returns. Coming in fun colors like bright pink and red, you can easily incorporate it into your lingerie look.

Size Range: 32A–46F | Material: Nylon, spandex | Padding: No | Colors: Black, brown, white, mahogany, red, blue, pink

Designed specifically for plus-size figures, this curve-celebrating bra is available in sizes 38C to 40DDD. We love that it has a comfortable wide band for a super supportive fit—even without the straps.

Available in black, beige, or white, you can wear it under anything from a strapless wedding gown to a slinky going-out dress to your favorite tank top. And you can keep it strapless or leave the straps on, depending on the neckline you're wearing.

Size Range: 32C–40DDD | Material: Nylon, spandex | Padding: Yes | Colors: Black, beige, white

Besides the size, you also want to make sure the bra is the right shade. Wearing a bra that's too light, especially under a dark dress, will be obvious when you're taking scores of photos. While many lingerie brands offer a single "nude" shade, this Black-owned brand makes undergarments to match a diverse range of skin tones, from dark brown to caramel to tawny.

Made from Italian microfiber, this bandeau bra is the perfect soft and seamless style. Unsure of your correct shade? Use the brand's shade guide to find your ideal match.

Size Range: XS–XL | Material: Polyamide, elastane | Padding: No | Colors: Dark brown, medium brown, caramel, tawny

If you're opting for a wedding dress with a plunging neckline and an open back, this backless and strapless bra is a smart choice. Adhesive, clear straps work to secure the bra in place while a deep-V silhouette ensures a flawless fit.

You also have the option to leave the straps off if you want to keep your shoulders completely bare. The silicone adhesive clings to your skin without feeling uncomfortably stiff, and it'll continue working well beyond the first wear.

Size Range: A–D | Material: Nylon, elastane | Padding: Yes | Colors: Black, beige

Donning an impossibly chic slip dress on your wedding day, at your bachelorette party, or on your honeymoon? This virtually undetectable bandeau bralette might be the undergarment you need.

The smooth microfiber fabric promises to lay flat under any satin dress or slinky slip or gown with pin-thin straps. It would also work with an off-the-shoulder style.

Size range: S/M–M/L | Material: Nylon, spandex | Padding: Yes | Colors: Black, brown, caramel, beige, white

Rocking a backless gown? This revolutionary undergarment features a virtually invisible adhesive band and seamless cups for a flawless no-show look. Its push-up design gives you an extra lift while the adhesive adheres to your skin without irritation.

We wish this bra came in more than one color, but the soft beige color works under white and blush gowns. Just a heads up, it runs slightly small, so you might want to order a size larger than you normally wear.

Size Range: B–H | Material: Polyester, spandex | Padding: Yes | Colors: Beige

You heard it here first: Strapless bras can be both fashionable and functional. This style from Adore Me is as sweet as ever for the bride-to-be with a romantic aesthetic and features a rose balconette and delicate, floral lace.

We love that it comes with straps, allowing you to wear it on multiple occasions beyond the special event you have in mind. Not only that, but the straps can be worn in different ways, including one-shoulder and cross-back.

Size range: 30A–38DD | Material: Polyester, nylon, spandex | Padding: Yes | Colors: Black, beige, brown

How We Tested

We spent hours researching today's best strapless bras and putting them to the test. We wore them consistently for two weeks before carefully selecting these highly rated options. Our tests included numerous styles and cuts in a range of cup sizes with varying features, like underwires, padding, adhesive, and removable straps. Each bra was tested on at least two people with different chest sizes, including one small to medium (A-D) and one with a fuller cup size (DD+). We wore the bra for a minimum of four hours per day for the duration of the test. Bras were also then washed and dried.

Part of the test included dancing and jumping to evaluate how much support they offered. Additionally, we measured the bands before and after wearing and washing to see if they stretched or became damaged. Then we narrowed it down to the best-performing strapless bras for all dress styles, cup sizes, skin tones, and occasions.

What to Look for in a Strapless Bra

• Fit: If there's one thing we know, it's that there's nothing more uncomfortable than wearing a strapless bra that doesn't fit properly. And almost 80 percent of women are actually wearing the wrong bra size, according to Cohen. To ensure a perfect fit, it's important to know your measurements and to refer to a brand’s fit and style guide.
• Supportive Features: For a comfortable yet supportive fit, go for bras with gentle boning and an underwire that doesn't pinch. If you're worried about a runaway strapless bra, select styles with a no-slip grip or adhesive cups.
• Style: The style of the strapless bra you choose ultimately depends on your dress. Wearing a backless dress? Bras with clear, adhesive bands and seamless cups are perfect for a flawless no-show look. And if you're looking for a no-fuss bra to wear under a slip dress, consider bandeau styles crafted from breathable, butter-soft materials that feel like next-to-nothing when worn.
