Picked this up from another posher. I haven't decided whether to keep it or not but this is what it will take to pry it from my hands. I have one of the other summer mesh dresses in an XL. I'm top heavy & can't wear fitted dresses without stretch. Otherwise, I wear a L in most skims: TL;DR I think this will fit L to 2X depend on your comfort level. I think they run a tad small.
