I just think the haircut, the scowl, the tie knot which is so out of proportion to the cut of the suit. Many (including many of the "man on the street" pictorials that Sartorialist has graced us with) have found ways of dressing unique and spectacular without looking so contrived. Dunc's been scowling for years. It's just the way he is. And he's sported a faux hawk for about the same amount of time. I think it generally works for him (and for some others). On second look, I noticed the patch pockets -- I loathe patch pockets on any jacket, especially a suit jacket. Still generally like the overall look, but don't care for some of the details.
