Obviously, the runway is prone to provocation and nudity is ok but no normal woman would wear once of these tops without something underneath. I've also been seeing lots of sheer button-downs with semi-sheer pockets over the breast-area. I suppose this is a more subtle way of covering up.

I'm really liking this trend. I think it has something to do with the ambiguity of the transparency. I love the exposure of skin without it being obvious.
