A nephew of mine begins his Ph.D. program at Michigan this Fall. I reminded him that he'd need a tweed jacket and recommended a look at the film The Good Shepherd for a professorial example. When I went back to look myself, I was struck by something I hadn't noticed the first time. Costume designer Ann Roth has Sir Michael Gambon, who plays the English professor, in a double breast pocketed odd jacket. Never saw one of those before.
Does one wear it with two pocket squares or leave them both empty?
