I actually find that ambiguos attitude of the clothing quite fresh and ahead of it's time again... I mean, noone on the market is making clothes like these that both men and women could wear.
I do have a problem however, seeing a girl clad from head to toe in Dior Homme... I've seen it a couple of times when they wear the jeans with the sneakers and I think it has something die-hard-lesbian about it, when you interpret it in a too sporty looking manner... I like to think of it in a context as YSL should be, menswear clothing adapted by women and given a slightly erotic, provocative, ambiguous touch.
