Paris in the '70s was running at full tilt -- a new order was coming into view amid hedonism, ambition, and outrageous decadence. This was a fashion revolution, the beginning of fashion as rock-star spectacle, and the world went wild for it. Alicia Drake writes about the dramatic collision and rivalry between two titanic geniuses, Yves Saint Laurent and Karl Lagerfeld, whose clashes sparked that tumultuous decade. Americans came to Paris in droves - from Andy Warhol and Jerry Hall to Bianca Jagger and Jessica Lange -- to be part of this irresistible moment. Others came just to catch sight of Karl Lagerfeld strutting around the cafs in his high heels and furs. Drake vividly captures the stunning highs and heartbreaking lows, the glorious achievements and dramas of an era when style reigned in the most glamorous of cities.
