Thirdlove’s New ‘Second Skin’ Bra Feels Like Nothing’s There in the Best Way Possible—Without Skimping on Support

For some of us, the phrase “unlined bra” sends a shiver of dread down our spines. Those with small boobs can get away with such sorcery, but those with a C-cup or above? They’re often a one-way ticket to Sag City, with a few stops at Nipple Town and Droopy Dale in between.

Until now. Thirdlove just launched an unlined bra that might just be the softest, most comfortable thing I’ve ever strapped my chest into, and it doesn’t waiver on support. The 24/7® Second Skin Unlined Bra ($72) is practically invisible under clothing, designed with a barely-there feel that nixes all drooping and dropping.

Thirdlove, 24/7® Second Skin Unlined Bra — $72.00

Sizes available: A-H and half-cup sizes; band sizes 32-44

Available in taupe and black.

The brand has won our hearts (and breasts) since it first made waves with its revolutionary line of half-cup sizes in sizes 32A-44H. From classic T-shirt bras, lacey bralettes, and compressive sports bras, Thirdlove has been dedicated to helping women wear bras that actually fit—a much-needed mission since 80 percent of women are reportedly wearing the wrong size.

Now, they’ve done the (almost) impossible: Designed an unlined bra that’s inclusive, supportive, and above all else, comfortable. “One of our most popular customer requests has been an unlined smoothing bra that can serve as an everyday invisible T-shirt bra,” explains Ra’el Cohen, Thirdlove’s co-founder and chief creative officer. “A good unlined bra is hard to find… We spent over two years designing and wear-testing this newest addition to our 24/7® collection.”

The Second Skin Unlined Bra is a totally smoothing and supportive style, sans any darts, padding, or molded cups. Made from buttery soft microfiber, it’s true to its name and contours close to your body’s natural curves as a second skin. “The magic is in our microfiber double ply smoothing fabric, it’s made from a special blend and designed for all day comfort,” says Cohen. “Most competitors use sheer fabrics that can leave you feeling exposed, or they need to incorporate darts which can cause lines and bumps under clothing. Our goal was to deliver a totally smooth and supportive style that lets your natural shape be the star.”

Why we love it

Cohen is right—the microfiber fabric is a game-changer, and honestly, feels so damn soft. Buttery is the only word I can use to describe how it feels, as it practically melts against your skin and makes you forget you’re wearing anything in the first place. And even though it feels naked, the double lining protects you from any unwanted nipple poppage in chilly situations.

But the sculpted support is even more impressive. Both the cups and bands hug your curves without causing any digging or spillage. Even under skin-tight T-shirts and bodysuits, you can’t see a thing. As a 34C/sometimes D, I really appreciate the subtle wire cups that don’t skimp on support, keeping me perky without overdoing it on the push-up front. Plus, the flexible nickel also contours to your body, so there’s no prodding or pushing while you wear.

That said, it does contain wire, so if you’re looking for something completely barely there, a bralette might be more your speed. Similarly, if you want something to wear under tank tops or dresses, a strapless or multi-way bra might be a better option, too. The straps on the new Second Skin bra are thick and hardy—perfect for support, but unfortunately not invisible under anything that’s adorned with a spaghetti strap. That said, you’ll want to wear it under T-shirts, sweaters, and long-sleeve tees all day. (And you’ll forget you’re wearing it, too.)

Tbh, I could wax about this magical, buttery bra all day long, but you should just try it for yourself. Step into your own second skin and buy the 24/7® Second Skin Unlined Bra here,in either black or taupe, in 32A-44H with half sizes, too.
