Goodbye to another fashionable season of Mad Men! After the season 5 finale aired on Sunday, we caught up with costume designer Janie Bryant to get the inside scoop on all the fabulous retro fashions, including the colorful dress Megan Draper (Jessica Paré) wore on the set of her first commercial shoot. "It was all about creating a 'peasant princess,' so to speak," Bryant said of the fairytale look. "The Butler shoe campaign is a play on the story of Beauty and the Beast. I looked at old Disney films, like Sleeping Beauty and Snow White and the Seven Dwarfs, for inspiration. The color combinations—the bright yellow and the red—are also very indicative of the later '60s." So pretty! Click through for Bryant's take on 35 more looks from Mad Men’s fifth season.
