Be Influenced by Mary-Kate and Ashley Olsen This Holiday Diane von Furstenberg always knew the woman she wanted to be. But something tells me the enigmatic Olsen sisters are still on their journey for self-discovery. In their New York Times bestseller Influence, which we've been raving about since day one, the sisters take us on a visual journey of people — photographers, designers, artists, writers, icons — who have influenced them. Fab is giving away eight autographed copies of book just in time for the holidays.
