So I wasn't 100% sure if these would fit since I couldn't find the size chart, so I took on educated guess.Large seemed the right size for me, my bra size is 36c while my butt is about size 12-14. I feel maybe the bra is a tad bit too big but it seems stretchy enough to go up one more size if you go down a size. The panties on the other hand are a bit too small but I have a larger butt so you know. As far as the material I am pleased with it, it seems cheap but not so cheap that its uncomfortable or will fall apart. I'm pretty happy with the product despite the size.
It's cute but really awkward fitting, it's hard to explain but the bottoms go way low both on the crotch and in the back but sit fine on the hips. The top isn't adjustable and is just slightly too big. I can still wear it but when I do there's a hint on being uncomfortable that makes it hard to enjoy.
