Don't Miss:

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, including the cut-out ivory silk crepe jumpsuit Jane Sterling (Peyton List) wore for her evening out with Roger. “She’s that character who can afford the latest fashions,” Bryant (inset) told InStyle.com. “For this scene, I wanted her to be in something very couture. This is a costume where we can really see that styles have moved forward.” Click through for Bryant’s take on more of last night’s looks, and catch the next episode of Mad Men Sunday, April 29th at 9/8c on AMC.
