The Twitter feed of Lucky’s editor-in-chief is a great promotional tool for the fashion magazine, but her 140-character quips never feel like a shill. Follow Chen’s feed and you’ll be along for the glamorous ride through a life filled with haute couture and Fashion Week shows. She also constantly engages with her followers, answering questions on her favorite products and style. Best of all, Chen’s online persona captures her laid-back attitude that manages to make fashion feel accessible even to those with only a passing interest. —Callie Schweitzer
