after reading other reviews, I already sized down from a M to a S, thinking a small should fit since it runs big (I'm usually a medium). No, the small still fits like an XL. It's very baggy and loose and not flattering. I may still be able to wear it with the whole "oversized tee " look since it looks like a crop top button up but probably not. I'm 5'2, 155lb, and DD chest.
