My top and bottom are always different sizes (med/large), but a large fit great at the bottom, and surprisingly the sheer top was too tight, especially on my arms. an XL at the top would have fit better since it DOES NOT STRETCH. I'm 5'5 168, with hips and B-cup bust

I mistakenly bought Xs but I didn’t bother to return it since I have a little sister. It’s very sexy and hugs your body.
