A new episode of Mad Men premiered last night, and we caught up with the show’s costume designer Janie Bryant to get the inside scoop on the fabulous retro fashions seen on the ladies of Sterling Cooper Draper Pryce. One of our favorite looks: the purple dress and dramatic vintage baubles Megan Draper (Jessica Pare) wore for her dinner date with Don. "Her whole costume design is about being modern and fresh," Bryant told InStyle.com of Megan's look. "I loved this dress for that scene." Click through the gallery for Bryant’s take on more of last night’s looks, and catch the next episode of Mad Men Sunday, April 8th at 9/8c on AMC.
