Base layers like bodysuits and plain T-shirts are great to have on hand, but tank tops with built-in bras might just be our favorite of all. This athleisure staple offers a two-in-one fashion solution for those days when you don’t feel like wearing a real bra, but still want some support. They’re also ideal for layering in spring and summer, and most styles offer a level of sweat-wicking too. It’s no wonder why I’ve seen them blow up on TikTok again and again.

Giving you the freedom to go braless, these tops perfectly balance function and style. You can wear them to your workout class or even layer them under a denim jacket or cardigan for a cute and comfortable look.

Our editors, who have tested tons of athleisure wear and workout clothes, have more than a few favorites to share, and I also tapped two fitness experts to help home in on what makes a great tank top with a built-in bra.

"This tank top is incredibly soft — I have to stop myself from putting it straight on once it's out from the laundry," associate editor Jillian Tracy says. "I love pairing it with the matching Beyond Yoga leggings for a relaxed athleisure look, but it's not so sporty that you can't wear it with a pair of jeans and a sweater too." The spaghetti strap top is made with a four-way stretch material that offers light support. It comes in sizes XXS to 4X.
