Love 'em or hate 'em, bras serve a routine purpose for many. But if poking, prodding, pinching underwires make you want to go bra-free, the wireless variety could be the answer. And believe it or not, many of today's best wireless bras can work for any cup size. Former Cosabella general manager Silvia Campello explains that wireless bras can be much less binding and constricting than their metal-boned counterparts. "They offer that free feeling of being supported and covered but not squeezed," she says.
We tested dozens of no-wire bras at home over two weeks to find the best available. Testers with various body types and chest sizes evaluated them based on fit, support, comfort, adjustability, care requirements, and quality. See which ones hold up—pun intended.
Our Top Picks
Best Overall
Honeylove CrossOver Bra
Excellent support and structure
Wide, smoothing band
Soft, comfortable material
Removable cup pads
Sides can cause chafing
Untraditional sizing
Materials: Nylon, spandex, polyester | Size Range: XS–3X | Colors: Runway, sand, vamp, astral, ruby, petal, +more
If support is a top priority, the Honeylove CrossOver Bra has your name written all over it. Thanks to its bonded design and extra-wide band, it offers a level of support comparable to that of a regular underwire bra. We were thrilled by how well it kept our breasts lifted and securely in place. This bra has removable cups. If you choose to leave them in, you'll appreciate that they're nicely made, fit well, and don't shift around or create awkward lines. Combined with adjustable shoulder straps and a hook-and-eye back closure, it really stands out for its customizability.
We found the material to be soft and comfortable, and appreciated how the wide band kept things in place. Although the bra comes in a decent size range, it doesn't follow traditional band and cup sizes, which makes it challenging to choose the best fit. (If you're in between sizes, the band recommends ordering a size down.) Still, we were impressed by the support of this wire-free bra and loved its overall look, feel, and shape.

Phoebe, tester with DD+ chest: "The band and straps are incredibly smooth and comfortable. I'm surprised the straps aren't digging into me more as they're certainly providing support and lift."
Most Comfortable
Chantelle C Magnifique Wirefree Bra
Comfortable for all-day wear
Soft, silky material
Layers nicely under clothing
Could provide better nipple coverage
Materials: Nylon, elastane | Size Range: 32C–42H | Colors: Black, ivory, nude sand, nude walnut, natural leopard, +more
Although none of our winners were uncomfortable, this bra really stood out in terms of comfort, to the extent that some of us forgot we were wearing it by the end of the night. The C Magnifique Bra has lightly lined, full-coverage cups, adjustable straps, hook-and-eye back closure, and a wide underband that provides structure and a smoothing effect without digging in.
Even without molded cups or an underwire, we were astonished that such a soft bra could provide so much support and lift. We liked how it looked nearly seamless under different types of clothing. The lightly lined cups don't offer complete nipple coverage, but considering how supportive and pleasant it was to wear, this didn't bother us too much. If you're looking for a wireless bra that you can put on in the morning and forget about until you change into your favorite pair of pajamas, this one won't disappoint.

Kelly, tester with 36H chest: "It was SO comfortable I couldn't believe it. I've never had much luck with wireless bras given I've always had a large bust. But the material is super silky and soft. It goes on easy and comes off just the same. There was no chafing to speak of, and the sides don't dig in."
Best Color Options
Skims Fits Everybody Scoop Bralette
Great range of nude shades
Super comfy; good for lounging
Decent support and structure
May not be supportive enough for large busts
Back doesn't adjust
Materials: Polyamide, elastane | Size Range: XXS–4X | Colors: Onyx, espresso, cocoa, bronze, ochre, clay, sand, +more
Skims is known for its inclusive sizing and expansive neutral color range with nudes that complement all skin tones. You'll also find brighter, punchier limited-edition hues. We found the design to be immensely comfortable, ideal for lounging and casual activities. The fabric felt smooth, and we liked the simple neckline and adjustable shoulder straps. Despite being a soft bralette without a wire or boning, it still provided some support. This bra doesn't have an adjustable band and may not be supportive enough for large breasts. In such cases, consider a sports bra specifically designed for larger breasts. However, we think it's a good pullover option for small to medium busts, or those with bigger chests looking for an at-home bra.

Chantia, tester who ordered a size small: "My boobs were secure and fully covered. There was no chance of a nip slip or anything like that. I was also surprised that it is as comfortable. The material of these really sealed the comfort for me. It also had a nice plush feeling on my skin."
Most Supportive
Wacoal Comfort First Wire Free T-Shirt Bra
Surprisingly supportive
Provides full coverage
Soft and comfortable against skin
Maintains shape after washing and wearing
Size range could be more extensive
Materials: Nylon, spandex, polyester | Size Range: 32A–38DD | Colors: Hot pink, black, shark, titan, rose wine, country blue, +more
We were so impressed with Wacoal's Comfort First T-Shirt Bra—it's everything we want a wireless bra to be. We found it surprisingly supportive (even for those with larger chests), not to mention ultra-soft and comfortable to wear for extended periods. We even wore it on a 16-hour flight and had no discomfort whatsoever. The underband is incredibly smooth, and we appreciate the adjustable straps and a hook-and-eye closure in the back. This bra offers full coverage, making it ideal for individuals with larger busts and those who prefer to minimize cleavage.

Taylor, tester with 34C chest: "It was SO comfortable. I was traveling for two weeks with this bra, and I slept in it on an overnight flight. It was never uncomfortable. It is by far the most comfortable bra I own. I forget I'm wearing it."
Affordable
Extra-wide smoothing underband
Shoulder straps adjust in front
Could offer a bit more support
Largest size is C cup
Materials: Polyester, elastane | Size Range: 30A–40C | Colors: White, butterscotch, toasted almond, navy ink, mauve, +more
On a budget? This affordable option fared very well in our tests. The Cloud 9 Comfort Bra offers full coverage with lightly padded cups, providing total nipple coverage without adding excessive bulk. We like how the shoulder straps conveniently adjust in the front, and the band is adjustable with a hook-and-eye closure. The underband is wider than average, helping to smooth your back and sides, just like shapewear, and it looks seamless under form-fitting shirts. The largest size is, unfortunately, a C cup. But all in all, we're big fans of this wallet-friendly wireless bra and would recommend it to those with smaller breasts.

Arielle, tester with 36B chest: "The band and straps were also surprisingly very comfortable. The comfort was comparable to my bralettes."
Best for Large Breasts
Knix WingWoman Contour Bra
Extremely supportive for large breasts
Molded cups offer nipple coverage and support
Extra coverage on sides and back
Material feels high-quality
Could offer more coverage in cups
Sizing is confusing
Materials: Nylon, spandex, polyester | Size Range: 28A–48H | Colors: Black, warm sand, sola, rose water
Finding a wireless bra for large breasts that offers sufficient support is challenging, but this one checks most (if not all) the boxes. For one, it's very supportive with excellent lift. We also appreciate the extra coverage on the sides and back, which provides a smoothing effect and prevents "sideboob" and spillage. What's more, the molded cups offer great nipple coverage—just know they're not removable. The WingWoman Contour Bra is available in a wide range of colors and a generous 99 sizes, ranging up to 48H. The sizing can be a bit confusing, though, so check Knix's size guide before ordering. Overall, we loved the high-quality look and feel of this bra and think the price is warranted for such a thoughtful design.

Amina, tester with 36D chest: "This wireless bra provided me with slightly less coverage but WAY more support than traditional bras I'm used to. The demi cups covered less breast tissue than my normal full-coverage cup bras. But my boobs bounced around so much less. I'm honestly shocked that this wireless bra could be so supportive with less coverage."
Best for Small Breasts
Pepper Limitless Wirefree Scoop Bra
Inclusive size range for small chests
Thick, supportive underband
Removable padding
Cups could offer more coverage
Not the most durable
Materials: Elastane, polyamide | Size Range: XXS–XL | Colors: Black, espresso, ecru, buff, sand, white smoke, +more
Those who are looking for bras for small breasts don't necessarily need (or may not want) a ton of support. If that's you, we highly recommend the Pepper Limitless Scoop Bra, which offers light support and subtle shaping. You can also remove the padding if you prefer a more natural bust shape or if a particular shirt calls for it. Although it appears to be a simple bralette, it still features adjustable shoulder straps and a hook-and-eye back closure. We like how the wide, stretchy band stays securely in place, while the mesh sides and front keyhole provide breathability. It might not be the most durable bra, as we noticed minor pilling and metal discoloration after washing it a few times. However, the cup shape held up well. All things considered, the Limitless Bra is a prime choice for A, B, C, and maybe even some D cups.

Anna, tester who ordered a small: "The bra was very supportive for a variety of activities. I wore it while traveling throughout Asia for two weeks, and we were hiking, walking, occasionally running to catch a bus, and the bra was perfectly comfortable, breathable, and supportive."
Best Full Coverage
Soma Embraceable Full Coverage Wireless Bra
Full coverage and support
Keeps breasts lifted and secure
Doesn't create excess bulk on large breasts
Looks great under clothing
Could provide better nipple coverage
Smallest size is C cup
Materials: Nylon, spandex | Size Range: 34C–44H | Colors: Warm amber, adobe rose, mochaccino, black
If you're looking for a wireless bra with generous coverage, so you don't have to worry about spilling out or showing lots of cleavage, this might be the one. It has all the features we want in a bra: adequate support, adjustability, an extra-wide underband, and all-day comfort. The cups are unlined, which is great for those who don't want bulky padding, but they still provide some shape. To our surprise, it did an excellent job at keeping low-hanging breasts lifted and secured in place without making them look too elevated or unnaturally shaped. The smallest size is a C cup, so folks with smaller busts will want to keep scrolling. Overall, we think the price is more than reasonable for such an impressive and comfortable design.

Chelsea, tester with 42DD chest: "I was shocked at the support the wireless bra provided. I always thought I needed a wired bra because of the size of my chest. My breasts naturally hang pretty low, but this bra was very flattering and made my breasts sit very nicely."
Best Wireless Push-Up Bra
Aerie Sunnie Wireless Push Up Bra
Ideal level of lift and push
Comfortable yet supportive
Runs true to size
Potential spillage
Materials: Recycled nylon, spandex | Size Range: 30A–40D | Colors: Sands, ballet pink, glacier gray, true black
Wireless push-up bras aren't exactly known for comfort, but this one from Aerie is an exception. We liked the soft, exceptionally stretchy feel and appreciated how the seamless, tag-free design wasn't at all scratchy. The padded cups offer medium lift and push (meaning pushing your boobs together slightly to create cleavage). It also looked entirely smooth beneath clothes. We found the sizing to be accurate and were amazed by how much support this bra provided in the absence of an underwire. If you're looking for a reasonably priced wire-free push-up bra that gives your bust some oomph, the Sunnie Bra is a stellar choice.

Sarah, tester with 36DDD chest: "As a large busted gal, I love it! My chest hangs pretty low, which is something I'm a little self-conscious about, so I was beyond satisfied with how this lifted and shaped it. It's comfortable, supportive, and super soft, which is more than I can say about my underwire bras. And the fact that it gave me lift without making my chest look ridiculous is incredible—I am so happy to have found a wireless push-up bra that I can actually wear."
What to Look for When Buying Wireless Bras

Byrdie
A good wireless bra can elevate the look of your body and clothes. We recommend keeping the following points in mind to determine which wireless bra is right for you.
- Material: Wireless bras come in various materials, depending on your needs, but cotton underwear is well known for its comfort. "Cotton bras are soft and breathable, making them the perfect everyday bra," says stylist Catherine Bibeau. "If you are looking for a seamless night out, look for microfiber. It offers a smooth, moisture-wicking, snug fit. The most supportive fabric by far is nylon/spandex blends as they provide the perfect stretch, support, and shape."
- Support: Campello recommends looking for supportive features, like vertical support seams (aka bonding), thick adjustable shoulder straps, hook-and-eye back closure bonded cups, and a wide underband. "The band is 90% of a bra's support," she says. "I personally like a bit of a wider band when it's wireless to accommodate for the lack of wire and to help it stay flush on the ribcage so it doesn't ride up under the boobs." For added lift, consider a wireless push-up bra with padded cups.
- Adjustability: Bibeau recommends features like adjustable straps and hook-and-eye back closures that let you customize a bra for a more exact fit. These features can also make it feel more structured and less like a sports bra or bralette. And since bras are known for relaxing and stretching with continued wear, this allows you to tighten them as needed.

How We Tested Wireless Bras
Below are the features our editors and contributors evaluated to determine our top picks.
- Fit: No matter how well a wireless bra is designed, it must have a comfortable fit to do its job effectively. We considered which wireless bras offered adequate coverage (compared to a traditional bra) while observing if each style fit our bust correctly. We also identified which bras suited different outfit types, awarding points to styles with a large selection of sizes.
- Flexibility: One major plus of wireless bras is the flexibility they provide (aka no wires poking at your ribcage). We ensured that each option on this list allowed for a free range of movement and tracked whether the bands and straps still provided the support we needed. We also noted the comfort of each bra, disqualifying options with features or materials that caused irritation.
- Quality: A well-designed wireless bra is an essential piece for any wardrobe—it provides support while offering ultimate comfort. We searched for options made with high-quality material, awarding points to bras that held up well after washing with no signs of pilling or stretching. We also assessed the value of each bra, noting if the quality aligned with each price point.
