Season 4 of AMC’s Mad Men premieres this Sunday, and Maxim is celebrating the show's sexiest secretaries and hottest housewives who inspire men everywhere to live the Don Draper dream. Wondering why you should tune in? January Jones returns as Betty Draper, the formerly wifed-up cutie who is taking 1964 by storm as the most delicious divorcee to hit Madison Avenue. Knock back an old-fashioned and feast your eyes on our favorite sixties suburban seductress. Cheers!
