An ex-Lagerfeld assistant has penned a revealing tome about the iconic designer who heads a namesake ready-to-wear line as well as Chanel. And it doesn’t look as though 37-year-old Arnaud Maillard is holding much back about the Kaiser. Titled Merci Karl!, the book, as Maillard puts it, intends to reveal “a different side” of Lagerfeld. Specifically, the side that “needs an eternity to get ready in the morning,” Maillard told Germany’s Spiegel. As for the distinct narcissism: “he takes photos of himself at every photo shoot and puts them everywhere. He surrounds himself with a kind of royal court, nobody disagrees with him.”
