This one's a no brainer. Since making her debut in the show in 2007, Megan's been considered a style icon. In fact, creator and executive producer Matt Weiner told The Hollywood Reporter that the black dress Megan wore during her "Zou Zou Bisou" performance at Don's birthday was "knocked off" and sold in stores within three weeks after the episode aired.

Don, the ad exec, is a master of the suit and tie look (pre-Justin Timberlake) and, as we found out, just as stylish outside of the office. He and Megan are definite throwbacks to the 1960s and together, they keep things interesting on cable TV.
