Very true Venom. She does have shoulder plates on under that which are tied to the main dress, plus a bracer on the arm with the dagger which you can partially see.
Both the T&A (tits and ass) comments, it is anatomically correct, any differences in appearance are due to the lighting and outfit. (believe me, a friend of mine in school looks completely different depending on her outfit and the lighting... hrrrmm... umm you maybe didn't need to know that)
I also agree Venom that the nose is the real trick, that and the eye lines, I'm still trying to get down the proper look so it seems like a painting and not a plastic-looking 3d model.
