Mad Men’s Betty Draper turns 35 today! January Jones grew up in Sioux Falls, South Dakota, where she worked at a Dairy Queen before moving to New York to take her turn—just like Betty!—as a model. Now starring alongside Jon Hamm, Christina Hendricks, Elisabeth Moss, and the rest of the show’s acclaimed cast, Jones moved beyond mod to become one of Hollywood’s most stylish, with a look that encompasses everything from Draper-esque mod dresses to high-fashion gowns as Versace’s frontwoman. Celebrate her big day by seeing how she’s transformed over the years in the gallery.
