Visible Influence: 1960s Slim Suits
While slim suits had already been creeping back into men's fashion, Mad Men pushed them into our living rooms. Premiering in 2006, main character Don Draper was "the man every woman wanted, and every man wanted to be" for a whole new generation. Granted, while some of his points of view would be considered outdated, his personal style was 100% modern, and inspired normal guys to dress in slimmer cuts, get slicked-back haircuts, tie bars, and proper pocket squares. Draper's influence has even seen Mad Men-inspired suits pop up at shops like Brooks Brothers and Banana Republic.
