I love fitted crop tops and this one is absolutely perfect. I'm a 32D and the size 4 fits perfectly. It holds everything in while being light and still has that "almost feels like I'm wearing nothing" feel that other Têra Kaia bras have. It's my new go to for crag and gym days :)

I've worn these swimming and hiking and they're perfect! I'm a 10/12 typically and the 8s fit me perfectly. Love the versatility & comfort.

I love the fit, especially around my shoulders. There aren’t pinches and there are no muscle/fat squishes from tight or inflexible straps. Not gonna lie, I wore the same bra 4 days in a row after it arrived.
