Betty Draper, "Mad Men"Signature Style: Retro charm. January Jones, the actress who has played Betty Draper (now Francis) since 2007, has said that putting on her character's early 1960's garments is a key part of her process. "I get into the girdle, the bra with the pointy cups, the stockings, the heels, the big dress...and I'm halfway there." Why We Love Her: Betty's retro full-skirted ensembles have had a profound effect on current fashion, which is perhaps part of the reason January has said she hopes the action doesn't continue into the 1980's. "I don't want to see Betty in Spandex." January Jones' Transformation Carin Baer/AMC
