I just tried on a small (on the advice that one should buy shapewear one size too small for optimal compression) and couldn't get it past my knees.  I just ordered a medium but I am thinking I may need a large.  I will update when it arrives.  FYI I am 5'9" and wear a size 8/10 in clothing.  It looks just as pictured--very pretty.

Oh and I am a woman (writing on my husband's account:)!
