This has zero stretch, you prob want to order a size up. I got normal xs and it is tight. Also, I think would be smoother at the zipper going up one size as it lays funny if tight. It is super cute, awesome cut over all. The green is sublime, just know it is sheer so nude undergarments will be needed. I am not wearing what I would wear underneath, but does show how it is sheer. I have black boy shorts and pink sports bra on (DEF was just for quick try on)
