4 Cool-Girl Activewear Brands Hailey Bieber Has Been Spotted Wearing, and What to Buy From Each
Chic, easy, and It-girl approved.
Hailey Bieber's style is always polished and chic—and her approach to sportswear fits into the same category. It's intentional, often including streamlined silhouettes and sophisticated details that offer a refined take on the gym aesthetic.
Bieber always makes it a point to reach for elevated performance pieces—like layered tops, criss-cross sports bras, and barely-there shorts—that effortlessly transition from mid-day sweat sessions to quick coffee runs in West Hollywood. She's not just after functional pieces, but silhouettes that serve as an extension of her personal style. Best of all, the Rhode founder gravitates towards accessible labels, including Form, Alo Yoga, Set Active, and Wiskii. (AKA the in-demand lines already flooding your For You page.)
Ahead, shop the athletic brands Bieber can't stop wearing. I've already added the labels to my closet, and they're too good to ignore.
Form
WEARING: Form Criss Cross Bra ($62)
Bieber's off-duty uniform regularly spotlights this cult-favorite athletic brand, which has sold out of its most popular styles—like its layered bra—more than once. It’s easy to see why: flattering fits, sleek neutral hues, and effortless workout-class-to-coffee-run looks never miss.

Alo Yoga
WEARING: Alo Yoga 3-Inch High-Waist Airlift Shorts ($84)
Los Angeles-founded Alo Yoga offers elevated workout silhouettes that easily transition from studio to street. Bieber isn't the only one reaching for the understated activewear, either; BFF Kendall Jenner, Bella Hadid, and even Taylor Swift have all reached for the chic styles. And if you're scrolling Instagram, chances are you've come across at least one of the brand's sets.

Set Active
WEARING: Set Active tank top and shorts
All of the cool girls wear Set Active, a brand offering polished workout sets in everything from two-toned fabrics to sea-foam green hues. By seamlessly blending comfort, function, and style, the label delivers obsession-worthy designs that often sell out the moment they drop.

Wiskii
WEARING: Wiskii Colorblock One-Piece Long Sleeve Top ($98); Form Fold-Over Pants ($87); Salomon XT-6 Sneakers ($180)
Activewear and athleisure brand Wiskii is popping up on every fashion person's feed, offering fashion-forward pieces complete with thoughtful details (think layered sports bras and scalloped edges). It's no wonder Bieber gravitates towards the brand—it's where elegance and performance meet.
