Mad Men has a major modern-day fashion following, thanks to costume designer Janie Bryant’s penchant for chic, ladylike designs—and now you can own actual dresses from the show! The gold brocade dress worn by Don’s onetime paramour Bobbie, the teal evening gown that Betty wore to a premiere party, and the green number Joan wore on the now-infamous lawn mower episode from Season 3 are all being auctioned off for a good cause: to benefit the Lung Cancer Program at City of Hope. The 10-day eBay auction, which begins at 10 PM EST tonight, will also feature props from the set, like vintage furnishings. If only they were auctioning off a date with Don!
