One of the lesser talked-about trends to emerge from the rise of athleisure and the relaxed dressing of the pandemic is that lack of structure and formality has carried over into bra styles as well. Women are increasingly rethinking stiff wired bras and opting for softer, more comfortable cups. Fortunately, wireless bras have come a long way from the basic bandeaus and simple pullover styles of the past. Today, the best wireless bras offer support along with a flattering silhouette and all-day wearability.

The right wireless bra—like this one from Cosabella—can be transformative by offering support, an ... [+] all-day fit and a sexy silhouette.

Still, shopping for an unstructured wireless bra can be challenging because you likely still want something engineered to enhance your shape and provide lift. After all, the whole point of a wire in a bra is to separate the breasts and encourage roundness. But there are many modern bras that hold and sculpt without a wire—for both small and large cup-size women—and they’re typically a lot more comfortable to wear than other options. Here, our round-up of the best wireless bras on the market now, whether you’re looking for a minimalist bralette, a padded push-up or an everyday t-shirt bra.

Sizes: 32B-38F | Colors: Black, tan | Materials: 94% nylon, 6% spandex

Opting for a wire-free bra means no wires poking and pressing against your skin. “This bra has a less rigid fit, and buyers love that it’s comfortable yet supportive,” says Christina Faraj Savarese, owner of The Bra Fit Expert in Cornwall, NY.  The sheer detailing is enough to inspire anyone to ditch an underwire since it adds an element of the unexpected to an otherwise very functional style.

This affordable bra gives you the comfort of a soft, elasticized waistband,\ and the sexiness of plunging stretch cups with lace. “This two-toned bra is gorgeous, you can get matching underwear if you choose, and it has a J-hook so you can wear it as a racerback if you want,” says Savarese. “The only drawback is that it fits a limited cup size from B through a full D but the ribcage size goes from 30 to 42.”

A couple things make this bralette especially popular with women with a curvier shape: It has wide straps that don’t dig in, side slings and a power mesh lining for extra support. “This bra is popular because it’s functional, comfortable and absolutely beautiful,” says Savarese. “The cup range goes all the way up to an I cup.” It also has matching underwear if you want a coordinated look.

Sizes: XXS-XL | Colors: Tan, black, rose, blue | Materials: 93% polyamide, 7% elastane

Smaller-busted women sometimes have issues with wireless bras riding up and squishing their chest. But Pepper bras are specifically designed for small sizes, and this style provides a little lift and a smooth silhouette under clothing. In addition to the wire-free construction, there aren’t any darts or seams to cause irritation, poking, itchiness or rubbing.

For times you want to wear a V- or scoop-neck dress or top, Skarlett Blue’s wireless plunge style has you covered, and gives you some extra volume. “This bra works well for small- to average-size-chested women,” says Savarese. “It’s comfortable because it’s seamless, and it provides a little pushup without a wire, which can be hard to find.”

Sizes: 30C-40B | Colors: Rose, seafoam | Materials: 81% nylon, 19% spandex

Everyday, comfy t-shirt bras are a necessary staple in your underwear drawer. “This bra has full coverage and is lined but it’s not thickly padded,” says Savarese, so it creates a more natural look for daily wear. Reviewers love how the deep V, plunge-style prevents uniboob.

For when you want shape without an aggressive amount of padding, molded cups are the way to go. This bra from French designer Simone Perele is made from soft microfiber that’s smooth under tees, and the bra gives a subtle lift—without making your breasts sore after wearing it all day. “We recommend this bra because it gives your chest a more comfortable natural shape,” says Daniella Di Ubaldi, buyer at Petticoat Lane in Greenwich, CT. “It provides good support and coverage without the wires that cause discomfort.”

Sizes: S/M, M/L| Colors: Black, white, ivory, caramel, mocha | Materials: 78% nylon, 22% elastane

This bralette offers next level comfort with a microfiber front and cute style with the scalloped lace detailing in the back. Because it’s a racerback style, it works for a variety of tanks, and the adjustable straps offer extra precision for fit and just the right amount of lift. “Most customers say this bra ‘feels like wearing nothing,’” says Di Ubaldi.

“This is super soft and has an under-the-cup and side sling that acts like an underwire and gives good separation and shape,” says Courtney Killpack, owner of Bra Fittings by Court. It works especially well for fuller breasts while you’re pregnant and has quick release clasps for nursing—and some users even wear it as a regular day-to-day bra, too.
