Being a shopping editor at Cosmo means I’m constantly surrounded by the newest fashion drops and trying practically every new launch—especially in the activewear world. I’ve tested more brands than I can count, cycling through high-performance leggings, ultra-supportive bras, and cute matching sets to figure out what works and is worth your hard-earned money. So trust me when I say I thought I’d seen it all, until I spotted a pap photo of Hailey Bieber (the internet’s reigning style muse) wearing a workout top I’d never seen before. Naturally, I had to know everything about it.

What immediately caught my eye is that it’s a two-in-one piece. An off-the-shoulder, long-sleeve top with a built-in halter sports bra that honestly looks chic enough for a night out. The $98 color-block top is from WISKII—the brand behind Taylor Swift’s iconic denim dress from her “I Can Do It With a Broken Heart” rehearsal—and comes in three other gorgeous colors. Honestly? I need one in every shade.

As chic as the top looks, it’s also built for serious comfort during workouts. The fabric is buttery soft with a 4-way stretch that lifts and sculpts, so it feels like it was made just for you. Plus, it’s breathable and moisture-wicking—meaning when you sweat, you won’t feel like you’re wearing a soaked towel. (I know you know the feeling.)

They’re selling out fast, which isn’t surprising—anything Hailey wears under $200 basically disappears overnight. Some sizes are available right now, and some are for preorder, and I’d snag those immediately. But the other colorways in all the sizes are still in stock… and you'd better move fast because, full disclosure, I’ve already got them in my cart.

Yeah, I need every single color...
