I’m attending this evening’s black-tie premiere of the second half of the final Mad Men season, which will debut on Sunday, April 5th. The first-anywhere showing of “Severance,” the first of the last seven episodes, will screen at the Dorothy Chandler Pavilion with an outdoor “Black and Red Ball” to follow. The invitation says that “guests are encouraged to dress in garb inspired by the period show”…meaning what? One way or another I’m going to hunt down Matthew Weiner and Jon Hamm during the after-party and ask them to defend their no-sideburns policy for Don Draper, which I’ve been complaining about for a while now.
