Mad Men and the Ugly 60s

I saw the season premiere last night of Mad Men and what I was afraid of has happened. The ugly fashion of the late sixties is in the show now. Even Pete Campbell, Mr. Republican WASP himself, is now sporting sideburns. I guess Draper will be wearing a leisure suit soon. Please, for the love of Mike, just don't make him get a weird afro perm like Mr. Brady of the Brady Bunch.
