In the ultra-personal debate of bra versus no bra, wireless bras offer up a goldilocks compromise: They promise both the support of a typical underwired bra and the comfort of letting your boobs hang free of restriction. But all too often, in attempting to do it all, these bras do neither thing very well IMHO, either coming up short on support or pressing into your sides or, heck, underboob (there, I said it) much like a wired one would. That’s where the Zero Bra from In Common ($45) claims to set itself apart, providing wire-free structure with a “barely there” feel. The only way to quell my skepticism? Giving it a try for myself.
Ever since In Common launched in January 2022 as a line of comfort-driven, eco-friendly underwear and basics, the Zero Bra has quickly become a fan favorite. It gets its name from its low environmental impact; while most bra pads are made of polyurethane foam (aka a material made with Earth-harming petroleum), the Zero bra is made from sugarcane. That also means that its cups don’t contain any residual—and potentially toxic—chemicals that can often hang around after polyurethane production, like TDI and MDI.
To the touch, the bra is super soft, thanks to a combination of 90 percent Modal and 10 percent Spandex. And it features an antimicrobial finish to help ward off the smelly funk that can happen with any kind of garment you’re wearing directly on top of your skin.
Available in eight colors (including the usual suspects, plus a few brighter ones), the Zero bra comes in 19 sizes from 32A to 38DD—which, it should be noted, isn’t enough to make it wholly inclusive of larger chest sizes. To accurately test its efficacy for folks with breasts that fit into the above size range, I asked four other W+G editors to try their size and give their very honest opinions. Read on to see whether the In Common Zero Bra holds up to its promise…or falls, well, flat.
Betty Gold, Senior Food Editor
Size tested: 32A
“I gave up wearing bras right around March 2020 and never planned to go back, but the In Common Zero Bra might actually throw a wrench in that plan. I found it super comfortable and well-fitted—no slippy straps or digging wires—and appreciated that it was actually true to size (what a weird rarity in this genre of apparel). The fit was flattering and didn't... distort reality. The material was soft and lovely, too. Only caveat? It didn't excel at moisture-wicking in the hot sun.”
Kara Jillian Brown, Beauty Writer
Size tested: 34D
“This bra is a great and comfortable option. I love that it has a deep-ish cut, allowing me to wear it with dresses and tops that show cleavage. And even though it’s wireless, it provides good-enough shape. However, the bottom of the cups do look a bit saggy without the structure that underwire provides. There’s also some negative space under my boobs toward the center that wouldn’t be there if the bra had the structure [of a wired one] to contour to my sternum. But, this is something that isn’t noticeable through clothes.
I wouldn’t wear this bra under form-fitting clothing, as it doesn’t make me feel as lifted and together as other bras I have and love, but it’s great for T-shirts, flow-y dresses, and other casual options. And since the bra is free of lace and other trim and made from a smooth modal, it works perfectly under thinner fabrics.”
Samantha Leal, Deputy Editor

“The Zero Bra was definitely comfortable and soft, so that was a plus. For me, as a DD (DDD/F when retailers actually have my band size), my boobs felt like they could have used a bit more lift (also—band sweat is real here), and I think depending on how your boobs fall, you may feel you need more coverage in the middle or that it could flatten you out a bit. If your boobs naturally lay a bit further apart or are more teardrop-shaped than round, this will probably be a very solid T-shirt bra.”
Abbey Stone, VP of Content
Size tested: 34D
“I abandoned heavily padded bras along with the malls I’d buy them from in the 2010s, but in the decade since, it’s been difficult to find alternatives that truly give my D-cup chest support without the added bulk. In Common’s Zero Bra aims to provide lift without an underwire, instead relying on lightly lined cups (made from eco-friendly sugarcane!).
While I love the bra’s deep plunge and convertible straps, I can’t give the design full marks in the support department. I tried my usual bra size (34D) and found that the band didn’t lie flat under my breasts and the cups felt a bit too skimpy on the sides for my liking. It could be that a larger cup size would provide more coverage, or that this bra is best suited to those with smaller chests.”

When I first strapped this on, the band was what struck me the most. It's thick and stretchy without digging in the back and offers some added support in the front, too, running just below the cups. In more good news, the cups themselves fit nicely around my boobs without gaping in the way that so many cups do, near the top.
After wearing it for a full day on several occasions, I can also report that this thing stays comfortable with time (a particular win for the bra department), and the straps stay put, too, which has become a pet peeve of mine with other bras. You just shouldn’t have to tighten bra straps to the point of pressing into your skin for them to stay in place—but I digress.
As other editors have noted, though, one downside to the silky-soft fabric of the In Common Zero Bra is that it doesn’t fare as well in the heat as I might’ve hoped. Anyone who even remotely knows me will know I’m a sweater, and this bra got pretty sticky when that ultimately happened. Thankfully, it’s easy to keep it in great shape, regardless; to clean it, just machine-wash with cold water, and air dry.
Did editors forget they were wearing the Zero Bra while they were testing it out? Well, almost (minus the stickiness in certain sweaty scenarios, that is). Every tester called out its softness and comfort above all else.
That said, for folks with larger chests, it wasn’t always a foolproof support system. A couple editors noted that the lack of a wire, in this case, can create a bit of a gap near the center of the bra (where the band runs straight across, rather than lying flush to the skin). But if your breasts naturally fall more to the sides, anyway, this’ll be less of an issue.
The bra’s smooth fabric, convertible straps, and deep plunge were all among its most-liked features, making it a solid choice for wearing under T-shirts, roomy dresses, or in any other scenario where you’re really prioritizing breezy comfort over form. And for people with smaller boobs, in particular, it’ll likely do you one better, offering enough structure to swap in seamlessly for any of its wired counterparts—but with none of the wiry restriction, of course.
