Did a quick Google image search. He definitely dresses thoughtfully and to a formula, he’s a narrow lapels sort of guy. I’m not wild about his shirt collars, but they are not the skimpy button downs one sees everywhere. He needs to read a course of OCBD’s old blog entries.
It’s good to see a high profile man getting dressed properly and  avoiding the all pervading blue suit, open necked white shirt and no-tie look.
