I am told that this is the, or at least a, look nowadays:
In only a handful of seasons, Olivier Theyskens has successfully established Theory as a sought-after downtown label composed of cool items that girls really want to wear. A major highlight for Fall 12/13 are the WINTER SHORTS, ranging from trouser styles to even hot pants. And although they were spotted elsewhere this week [mid-February], pairing them back to sheer black hosiery is just the look that Theyskens’ girl will be spotted in 7 months out.
Um, thank you, Mr Theyskens. Your efforts are greatly appreciated. But that’s not at all what I was thinking when I said “winter shorts” at least, not when I wrote this.
