11 Best Wireless Bras We Tested for Comfort and Support 2025

Made from soft cotton with a wide, supportive underband, this bralette-style T-shirt bra offers just enough structure to keep everything in place, whether you’re lounging, layering under a tee, or wearing it on its own. The plunging neckline adds a surprising amount of versatility, especially if you tend to wear plunging styles, and the racerback straps help ensure a secure, supportive fit that won’t budge throughout the day.

“I’ve been more conscious about bra comfort after I was diagnosed with a fibroadenoma (a noncancerous tumor) in my right breast, so I’ve relied on this bra ever since,” says Glamour commerce writer Alanna Martine Kilkeary. “It’s wildly comfortable, isn’t too tight at the band, and gives me enough support without squeezing my boobs.”

Fellow commerce editor Malia Griggs agrees: “Even without underwire, this bra supports my 32D chest, thanks to the thick underband. The plunge shape works under tricky outfits, and the wide straps offer just enough back support.”
