The latest promotional photos for Season 6 of Mad Men, debuting Sunday, April 7 at 9 PM ET on AMC, shows the cast getting all dolled up for a spiffy night out on the town. Jon Hamm is back as Don Draper, who must lead Sterling Cooper Draper (they have to drop the Pryce from the company name now, right?) into a new era of advertising greatness at the tail end of the 1960s. Take a look at the cast, including Elisabeth Moss, Vincent Kartheiser, Christina Hendricks, Jessica Paré, John Slattery, Robert Morse, Aaron Staton, Rich Sommer, January Jones, Kiernan Shipka, Alison Brie and more looking their elegant best at a formal affair, before the Season 6 Premiere debuts next month.
