The thinking behind Vanessa’s risky outift is that there are two pieces of fabric to cover each breast and when one lies on top of the other it provides enough opaqueness that her bare boob beneath won’t be seen (as can be seen in this picture in her right breast). However, if one the layers somehow gets pulled to the side during the course of the evening leaving just one piece to cover her modesty, that would be inadequate as each piece on its own is transparent. Which is what’s happened here on her left, giving us this fabulous see through photo of her tit and nice big brown nipple. Yummy.
