Want to look like Don Draper without being a dufus? Have no fear. New men's suits are sporting some of the same designs worn by the golden boys of the fictional ad agency on TV's hysterically popular Mad Men. "Men's suit styles have dramatically changed, and the styling of the late '50s and '60s has been influential," said a manager at Brooks Brothers, which is selling Mad Men sharkskin suits. A trimmer, shorter suit is the key. But please, warns the Wall Street Journal, go easy on the Brylcreem.
