Tie, no jacket

With the new show, "Chuck" a seeming hit and Best Buy's integration of and thus spreading of the GeekSquad brand, geek chic is definitely hitting a fever pitch. Yes, I'm talking about wearing a button down shirt with a tie, without a jacket. Riding the train in this AM--and new phenomenon as many of you know--I noticed more than a few folks sporting this look. My hunch is that most were in IT.
