Underwire bras used to feel like a necessary evil. (There’s no way you’re getting that kind of support from a bralette, right?) Now, female-founded brand ThirdLove has redesigned the bra from the ground up, so underwires are no longer a necessity or an evil. Instead, they’re something we can wear comfortably, or skip altogether without compromising on support. ThirdLove’s Form 360 Fit™ Wireless Bra, which just launched, belongs to the second category.
Form 360 Fit™ Wireless Bra
$62 at ThirdLove

Like most of ThirdLove’s bras, the Form 360 Fit™ Wireless Bra is meticulously designed for maximum comfort, so it never digs, slips or rolls. That said, it sets itself apart in one major way: Built-in foam cups and seamless four-way stretch offer a shocking amount of support — without any underwires whatsoever.
Now, this isn’t the first wireless bra to promise support, but does it have enough support for bigger busts too? According to reviewers, yes — especially since the Precise Sizing™ system offers three times as many options that map back to your band and cup size (because, according to the brand, XS through XL isn’t good enough). “This actually supports me,” writes one reviewer who’s a G-cup. Others called it the best wireless bra they’ve ever worn. Currently, it comes in nine colors, both solids and marble patterns, all with adjustable straps and a padded, tagless hook-and-eye closure.
Still, maybe wireless just isn’t your thing. That’s OK. ThirdLove has plenty of other top-selling designs that, combined, have racked up more than 100,000 5-star ratings. With code CNN15, shoppers can get 15% off their first purchase through March 18. (Some exclusions apply, this offer can’t be combined with other discounts and it’s limited to one per customer.)

24/7 Classic T-Shirt Bra
$72 at ThirdLove

This is the brand’s No. 1 bestselling bra. Its brilliant features include silky, pleated straps that won’t slip, form-fitting underwire cups that won’t show under clothing and unbelievably soft micro-jersey material that actually stands up to daily wear. “Fits like a glove,” one reviewer writes. “I hardly know I’m wearing it.”
24/7 Classic Uplift Plunge Bra
$72 at ThirdLove

For lower necklines, there’s the Classic Uplift Plunge bra, which comes in sheer mesh panels or all-over lace — your choice. Either way, the deep-V design creates cleavage alongside comfort and support. Its signature half-cup sizes combined with removable pads help you personalize the fit.
24/7 Perfect Coverage Bra
$72 at ThirdLove

Need a little more coverage? As per its name, this bra delivers with its wide, cushiony straps, memory foam cups and double-layer U-shaped back. One reviewer calls it the “best full-coverage bra ever” because it’s “super comfortable, long-wearing and durable.”
24/7 Second Skin Unlined Bra
$72 at ThirdLove

You don’t need pads in order to get lift, support or coverage. The Second Skin bra is unlined for a minimizing effect, but its underwire and foam-free cups have still earned it the reviewer-awarded title of “unlined bra of my dreams.” Its thick, adjustable straps and smoothing fabric only add to the functionality.
Kinetic Impact Sports Bra
$78 at ThirdLove

The Kinetic Impact took the best qualities of a sports bra (flexible, breathable comfort) and combined them with the best qualities of an everyday bra (structured cups, adjustable straps and a hook-and-eye closure). You can even crisscross the straps for additional lift, but either way, its contoured cups provide bounce-free support during high-impact activities.
24/7 Classic Strapless Bra
$72 at ThirdLove

Reviewers are truly in awe of the 24/7 classic strapless bra. “It stays on no matter what, even after a night of dancing, without cutting into your skin,” one writes. Another raves, “I’m a 40G and this has been the only strapless I’ve ever been able to wear.” Nonslip silicone edges, body-conforming foam cups, half-cup sizes and convertible straps help you achieve the same results.
