Fair warning that this body suit is high cut on the side. If that's your jam, go right ahead, but I like my muffin top covered on all sides. I bought one size up and it is very stretchy so I easily could have bought my actual size if not a size smaller. It's a little see-through, but a sticky bra should work.

I bought a LARGE & XL but the XL fits more comfy. and it is stretchy. I’m 5’3-5’4 and more on the “fluffy thick” side. wear a size Xl in shirts too
