There’s no stretch to this at all. I have a bigger butt and normally wear L, this only comes in L/XL so I thought I’d be okay. It fit, but I could hear the fabric tearing as I was trying to get it over my butt. The top however is huge on me. I’m a 38 DD so I know it’s not my chest size. It’s just a coverup so it’s gonna serve its purpose so I’ll keep it and make it work
