Kaia Gerber Just Posted a Photo In This Iconic $15 Sports Bra

Whether you're Gen X or Gen Z, you already know that the ubiquitous Calvin Klein sports bra goes hand in hand with "effortless" and "sexy." And who better embodies these qualities than CK brand ambassador and professional cool-girl Kaia Gerber? Last week, the supermodel posted an Instagram photo showing off her Calvin Klein Modern Bralette (Buy It, from $15, amazon.com) and matching white undies with the caption "at home in my Calvins." (BTW, Gerber also just wore this Hailey Bieber-approved fleece jacket that you need to check out.)

With a stretchy elastic band and unlined cups, the unfussy, lightweight cotton bra is made to mimic the natural feeling of going braless — perfect for yoga sessions, walking the dog, and working from home. However, the sporty racerback design offers a bit more support around the house and for Zoom meetings and pairs seamlessly with leggings and loungewear. Even though it is technically a sports bra, Amazon shoppers say it's so soft and comfortable, they can even sleep in it without it feeling tight and restricting. And while this means the highly-coveted sports bra may not be suited for high-intensity workouts, such as running and HIIT, there's one thing that people with a range of breast sizes agree on: the comfort it offers.

The iconic Calvin Klein bra has won the hearts of fashion-minded celebrities and TikTokers, alike, and has been spotted on countless stars including Kendall Jenner and Charli D'Amelio. What's equally impressive is that the bralette has amassed more than 16,000 five-star ratings from customers on Amazon, who love that it doubles as a comfortable undergarment and a fashion statement. (Psst, if you're looking to build your athleisure lineup, this sports bra is also beloved by TikTok.)

"This bralette rocks," wrote one shopper, who noted that the bra is both lightweight and supportive, making them feel justified in ordering a couple more. Another customer, who struggled to find a comfy bra in the past, also remarked on how "soft and comfortable," the bralette is, adding that it "makes a great layer for days when I'm lounging." Even those who tried it on for the first time after receiving the bra in the mail, said they would buy it in every color.

A final shopper, who likes wearing the bra under a cropped sweatshirt, reminds buyers that, while this is "the most comfortable bralette in the world," it's not supportive enough to work out in. But, if you're simply in the market for a high-quality bra that's incredibly comfortable and fashionable (just look to the supermodels who swear by it), Amazon reviewers share that they wear this one "almost every day."

Just because the Calvin Klein bra has a fan club of A-listers, doesn't mean you have to fork over rent money to steal Hollywood's style. Believe it or not, the celebrity-approved design is currently on sale starting at just $15. With more than 20 colorways to choose from — including neutrals like black, white, and gray, as well as bold shades like orange, topaz, and pink — you may find yourself adding more than one to your shopping cart, and who would blame you?
