I like what Pavlos has going on here: the tie, the flag belt (you can barely see it, but it's cool), the casual rolled up sleeves.
I also like the book and the spread cut of his collar. It transforms a white button-down from the middle-aged office worker look to graduate student chic (that's a technical term).
I was trying to be surreptitious, but he noticed me. Maybe it has something to do with the fact that my camera was on flash.
