10 Best Strapless Bras, Tested by 60 Women

Sizes: 34–42, C–DDD | Materials: 80% nylon, 20% spandex | Colors: 2 | Convertible: Yes, straps included

Yes, this Bali bra is our best-performing style and our pick for best value — it currently costs under $25 and outperformed styles over four times its price. With lightly lined, full-coverage foam cups, it has an underwire for support and lift and silicone grips to help keep it in place, which testers especially appreciated. We had B, C and D cup size testers wear this bra and they all reported that it was a perfect fit.

This bra received the highest consumer score out of all the strapless bras we tested, with all testers giving perfect scores for running true to size, staying in place and being easy to take on and off. "I was pleasantly surprised by how much I enjoyed this, for a strapless bra," reported one tester with a 36C bra size. "I typically can't stand strapless bras because they feel uncomfortable and slide down, but this one stayed in place and I even forgot I was wearing it." Another tester with a 34D bra size said, "It gives you a little lift and doesn't give you that uniboob look that some strapless bras will give you."

Some testers noted that the fabric felt a little rough and wished it was softer. And while this bra washed beautifully in our Lab tests with minimal shrinkage, it stretched out a bit in our stretch recovery tests.

Sizes: 32–42, A–G | Materials: 71% nylon, 29% spandex | Colors: 5 | Convertible: Yes, straps included

Most strapless bras feature an underwire, but this wireless, strapless bra from Soma is designed to provide the same support without any wire. (The version of this bra with straps cinched the top spot in our wireless bra test.) The Enbliss strapless bra features molded cups to create a natural shape and ample lift as well as fabric that's luxuriously soft because it's lightly brushed.

Unlike most bras with three rows of hooks and eyes in the back, this style has five rows, so you can tighten it even if it stretches out. This is especially helpful as we did find this bra to stretch out a bit in our stretch recovery tests.

Testers especially liked the Soma Enbliss line for offering ample lift to create natural-looking cleavage without a wire that pokes and prods. "The fabric was buttery soft and smooth; I really liked it and was comfortable all day," said one tester with a 32DD bra size. Another tester with a 36B bra size said, "I liked that it felt very smooth and supportive, and fit nicely." It received high marks across the board for being comfortable to wear, supportive and staying in place from consumer testers.

Sizes: 30–44, D–I | Materials: 91% polyamide, 9% spandex | Colors: 7 | Convertible: Yes, straps included

Available in an impressive size range up to an I cup size, this Wacoal bra has been a top performer in our evaluations for years. We tested this bra both in 2017 and 2023 — and it continues to be a tester favorite. In our Lab evaluations, this bra proved to be durable, maintaining its shape after our stretch recovery tests and it didn't shrink or change appearance after laundering.

The thoughtful design, which includes a slightly padded bottom band to prevent any digging in, helps it feel supportive and comfortable throughout the day. There are also silicone grips along the top and bottom band of the bra to keep it secure. We especially appreciate the boning on the sides and the wider band to help provide ample support for larger cup sizes without any bulging or uncomfortable pinching.

One tester with a 38DDD bra size said, "Overall, the bra is great and the bra felt secure for someone with a larger chest." She also said, "I love the feel of the cups; they are so smooth and soft on my skin." Another tester with a 32G bra size said, "The cups were large enough and did not cut into my breasts." Both of these testers noted that the bra was more supportive when they wore it with the adjustable straps. Some testers also noted that the cups dug a bit into their ribcages a bit.

Sizes: 30–40, AA–B | Materials: 75% polyester, 25% elastane | Colors: 4 | Convertible: Yes, straps included

Those who have a small chest may be familiar with the frustrating gaping that can happen with underwire bras. Pepper designs their bras specifically for people with AA to B cup sizes to ensure a proper fit. The cups on this bra have a more shallow design to help prevent gaping, and a silicone strip along the band keeps it from any sliding down. The flattering balconette cups are lightly lined to enhance your natural shape and provide nipple coverage without feeling bulky.

One tester with a 36A bra size tried this bra and said it was a "total game-changer for small-busted women." Our testers with small cup sizes loved Pepper bras for providing a proper fit that feels comfortable enough for all-day wear. Although we haven't tested this exact style in our Lab yet, Pepper bras have previously shown signs of wear and shrinkage after laundering.

Sizes: XXS–4X (30–44, A–H) | Materials: 76% polyamide / 24% elastane | Colors: 12 | Convertible: No

Free of bulky padding, scratchy seams or stiff underwires, this simple Skims bandeau bra offers a comfy solution compared to traditional strapless bras. With a snug fit and smooth, stretchy polyamide and elastane fabric, this bra is available in eight different nude shades, so you can find a close match to your skin tone. Because this bra lacks any padding, it has minimal nipple coverage.

We have tested a variety of Skims bras, including this bandeau bra and the Fits Everybody T-shirt bra and push-up bra. Our testers applaud Skims' commitment to inclusivity with a size range that goes up to 4X and a variety of nude shades. "I loved the material and think it could be great for a casual bra," reported one tester.

Sizes: 32–44, AA–H | Materials: Nylon/spandex | Colors: 2 | Convertible: Yes, straps included

Featuring a classic design, this Thirdlove strapless bra offers lightly lined cups with an underwire for full coverage. It features a bit of padding around the underwire to prevent any uncomfortable digging in. The wide band with silicone grips on the top and bottom help keep the bra secure for a full day of wear. This bra is convertible with straps included. Our testers especially liked that it comes with two sets of straps: one matching the color of the bra you ordered and another that's clear.

Some testers found this bra to run a bit small. Thirdlove offers a unique sizing system with half-cup sizes, so we recommend reading the size chart closely to find your best fit. "[This bra] kept my boobs supported very well for a strapless bra," said one tester with a 34DD bra size. Another tester with a 32C bra size said, "This bra was very supportive and has the perfect amount of padding." One tester with a 32G bra size "thought it was smart the way they made the padding/lining thicker at the bottom to help keep your boobs up and it worked."

Sizes: 32–40, A–DD | Materials: 67% nylon, 33% spandex | Colors: 3 | Convertible: Yes, straps included

Strapless bras with boning have more structure and shape, which can make them stay in place better and feel more supportive. Like a corset, this Maidenform strapless bra has boning on the sides, meanwhile the lightly padded underwire cups create lift while staying hidden under clothes. The breathable mesh between the cups helps prevent overheating while creating a stylish silhouette. It features silicone grips to keep the bra from sliding down (which testers said really worked!).

All testers liked that this bra stayed perfectly in place. One tester said, "It is such a pain to pull a strapless bra up all day, but with this brand it didn't move an inch!" Testers liked using the convertible straps with one saying, "The straps were easy to remove from their loops." Another tester noted, "This bra was very supportive, but I do wish it had more lift."

Sizes: 32–38, B–DDD | Materials: 83% recycled polyamide, 17% elastane | Colors: 4 | Convertible: Yes, straps included

Victoria's Secret is known for their high quality push-up bras and this style is no exception. It features slight push-up padding and a lower neckline to create natural cleavage while staying hidden underneath lower-cut tops. Ideal to wear with practically any garment, this strapless bra can be worn in 12 different ways for ultimate flexibility, thanks to adjustable straps that you can switch to halter, one-shoulder strap, racerback and more.

A tester with a 32C bra size said this bra "stays up and doesn't fall down or move [and] it's comfortable!" She even said, "You honestly forget you are even wearing a strapless bra when you have it on (which is saying a lot)." All testers said this bra was true to size and easy to take on and off; plus, they loved this bra's appearance on its own.

One tester with a 34C bra size wore this strapless bra "with a spaghetti strap dress for a wedding and it stayed in place for the whole event (plus getting there and getting home), which was roughly 12 hours." Some testers noted that the padding is built-in and they would have preferred if it was removable.

Sizes: 32–36, B–G | Materials: 83% polyamide, 17% elastane | Colors: 6 | Convertible: Yes, straps included

Featured in our best lingerie brands, Cosabella makes beautiful bras like this strapless style designed with scalloped lace for a delicate, feminine look that pairs perfectly with the brand's matching underwear. This bra has an underwire for a supportive fit with full coverage cups to keep you lifted and covered. We appreciate that this style is available up to a G-cup size, but the band size range is quite limited, only going up a 36.

We haven't yet tested this new launch from Cosabella, but we have tested the brand's Never Say Never balconette bra and bralette, which feature similar lace detailing. Our testers loved Cosabella's lace with one saying, "It was a beautiful lace that felt soft to the touch." "I LOVED the sexiness and look of the bra," said one tester with a 32G cup size who tried the balconette style. "It is a 10/10 in terms of finding lingerie that fits and is sexy."

Sizes: A–G cup sizes | Materials: Cotton and silicone adhesive | Colors: 4 | Convertible: No

For tricky tops and dresses, a traditional strapless bra may not cut it. Sticky bras to offer coverage and a bit of lift and shape without any back straps, ideal to pair with backless or low-back dresses. Some testers, especially ones with smaller cup sizes, preferred to wear sticky bras or nipple covers instead of a bra. This Niidor adhesive bra includes two sticky cups that attach together to create natural cleavage. With proper care, you can rewear this sticky bra dozens of times!

This bra has over 21,000 Amazon reviewers with hundreds crediting this bra with being extremely comfortable to wear. "I wore it for a month last summer on vacation. Loved that I could wear it with any kind of top or dress," noted one reviewer. "It stayed in place even with the humidity in Europe." Reviewers with larger cup sizes gave mixed reviews: Some applauded its support, while others said it had an awkward fit.
