Let's just say it: Bras are uncomfortable. And sure, ditching the underwire sounds dreamy... until you're left with just a piece of flimsy fabric that doesn't provide any lift.

The good news: They do exist. After hours scouring the internet and shoving our own boobs into the most popular wireless bras, my Cosmo colleagues and I found the best wireless bras out there. Let's be honest, they may not hike your cleavage sky-high like a push-up corset would, but these bras come with rave reviews for all-day comfort and lift, too. And no, they're not just bralettes—these come in plenty of different styles, such as push-up bras, T-shirt bras, and pullover bras, while all providing both comfort and shape.

46,000 (and counting!) Amazon reviewers are obsessed with this wireless bra that supports and lifts your boobs without feeling constricting or even like you're wearing a bra at all. The comfy fit can be attributed to its super-stretchy fabric that retains its shape, even wear after wear. It's also super easy to take care of considering it's machine washable and needs no extra steps to maintain its shape and fit. But the best part? The underarm smoothing technology that makes all your tops lay perfectly. We're talkin' even under the tightest of T-shirts.) Oh, and it's $22—enough said.

Cons
- Band may stretch out over time
Why we love it: This bra delivers a natural lift and feels like you're wearing nothing at all. It's versatile enough for all types of tops and comes in a wide range of sizes.
Thousands of reviewers agree: This bra seriously feels like you're wearing nothing at all. With medium-coverage contour cups, this Soma style gives you a natural shape and plenty of support—plus, did we mention it's seriously comfy? I will wear this bra under my tight T-shirts, loose sweaters, and everything in between. My favorite thing about it is that, like a regular wire bra, it shapes my bust perfectly—it doesn't overdo it with a push-up (trust, there are days for that, too), but instead, it gives them a natural yet perky lift. It's my go-to, and I have yet to find an everyday bra that tops it.
- Material: 72% Nylon, 28% Spandex
- Size Range: 32-42, A-DDD
Pros
- Double knit fabric prevents the bra from being see-through and adds support
- The criss-cross underarm design keeps it from irritating your skin while smoothing it
- Smoothing side panels prevent bulging and rolling
Cons
- Though there isn't hardware on your straps, there still is a clasp on the back
Why we love it: It's buttery smooth and won't bulge or roll up—even under the tiiightest of tops. The size range rocks, too.
The genius behind this design can be attributed to its extra side coverage panels, smoothing back panels, and shaping contour cups. These features result in no bulging in the typical areas (i.e., your arms, and bra roll, which, to be fair, is totally normal—but if that's not your jam, this bra prevents it from occurring). There's also absolutely no hardware on your straps—meaning that it doesn't poke out at all under your clothing.

- Size Range: S-3XL Plus
Pros
- Comes in more than 20 colors
- Has wide, comfortable straps
- Moisture-wicking material
Cons
- Straps aren't adjustable
Why we love it: The wire-free design shapes with soft, stretchy cups and a stay-put comfort band. It's also breathable, smoothing, and moves with you.
You can always rely on Bali for A+ undergarments, and this bra is no exception. With its stay-in-place wide straps, moisture-wicking fabric, and soft foam cups, it's easy to see why this ideal T-shirt bra has racked up thousands of glowing reviews. I particularly love the four-way stretch fabric that makes it feel like my breasts are supported without any poking, prodding, or digging. Plus, even after I wash it over and over again, it still maintains its shape.

Stretchy fabric that hugs your skin just right, nice thick straps that don't dig into your shoulders, a slightly longer-line style that won't roll up, tons of cute colors with leggings to match—sounds like the sports bra of your dreams, right? Mine, too, and I found it—the Goldilocks of wireless sports bras—right on Amazon. Reviewers say the CRZ Butterluxe Bra is so, so soft and feels comparable to some high-end workout brands (you know the ones!), too.

Reviewers love the adjustable split straps, the medium-lift, the seven neutral colorways, and the fact that it's made with recycled fabrics (as well as the fact that it's almost always on sale). And our own editors at Cosmo love it just as much: "Aerie's Sunnie is the only bra I've worn for the past, like, 10 years," says Lifestyle Editor Hannah Chubb. "It's so comfy and soft that it feels like wearing nothing, and it's smooth and subtle under a T-shirt. I would recommend it to literally anyone!!"

"I swear by Lane Bryant bras because they have thick straps that don't dig into my shoulders and actually hold up the girls!" she says. The secret formula behind the bra? The cushioned, wide adjustable straps, as well as the increased airflow due to the vented design.
- Material: 8% Spandex, 92% Nylon
- Size Range: 36-54, B-K
How to choose the best wireless bra
Underwire bras may reign supreme when it comes to support, but you can still find plenty of wireless bras that'll give you shape and lift without pokey wires. And, no, a wireless bra isn't the same thing as a bralette. Wireless bras tend to have more padding and structure than bralettes, with molded cups to provide more of a contoured look beneath your clothes. When you're on the hunt for the perfect wireless bra, here are some things to keep in mind:
How should a wireless bra fit?
Not to state the obvious, but finding the right fitting bra is important, especially when it comes to wireless bras. As LIVELY creative director Sarah Sullivan says, "It should provide you the right support, coverage, and be comfortable all day long." Gaping cups, slipping straps, and too-tight bands will all prevent you from experiencing all-day comfort—which is what wireless bras are all about!
What's the most comfortable material for a wireless bra?
You get what you pay for, and while high-quality bras can be pretty $$$, they're well worth the investment. As Sullivan points out, "A bra may be great at first but lose support or comfort after a little wear." Cotton and microfiber bras are best for everyday wear, while nylon and spandex are also great options if you're looking for something stretchy but super-durable. And you probs wanna avoid thicker or textured fabrics that'll show under your clothes, especially if you're going for a seamless look. Speaking of which...
What (else) should I look for in a wireless bra?
You might want to avoid decorative details. Ya, frills and lace are fun, but they won't seem so cute when you can see 'em sticking out through your clothes. Seamless, molded cups with little to no extra detailing—like darts, ribbons, or bows—will give you the smoothest silhouette, but as Sullivan says, "Don't sacrifice style; this bra should work hard, but it should also look and make you feel good!" Basic doesn't have to mean boring, and these beloved wireless bras prove it.
