I love a good fashion documentary. The best ones, like Unzipped or Valentino: The Last Emperor , understand that fashion is chaos disguised as elegance. There is drama, deadlines, panic, ego, tears, last minute miracles. The camera catches people sweating as much as it catches them styling. That is the fun of it. So Marc by Sofia arrives with a lot going for it. You have Sofia Coppola behind the camera and Marc Jacobs in front of it. Friends for decades. Creative collaborat
