A genius creator who was extravagant, insatiable, and lonely, he underwent a thousand metamorphoses. This biography retraces his multiples lives, and through them, a history of fashion. The fruit of much inquiry, it is based on long two interviews with Lagerfeld and the accounts of those close to him, as well as figures from the fashion world.
