Mad Men fans — present! — who visit Banana Republic between July 21 through Aug. 11 have a shot at appearing on the AMC series. Interested? Me too. During your shopping session, pick up a ticket to enter to win a walk-on role in an upcoming episode, as well as a $1,000 gift card from the store. Use the ticket code found on a Style Guide you'll be given profiling the characters to enter the casting call at madmencastingcall.amctv.com.During this period, Banana's mannequins will be dressed in modern takes on the classic '60s style, and store windows will feature photos from the show. "Style and fashion are at the core of Mad Men with its 1960s aesthetic highlighting the classic silhouettes that are still popular today. Banana Republic is known for its modern takes on these classics . . . so the partnership is a natural fit for both brands," said Jack Calhoun, president of Banana Republic. Agreed, can't wait.
