New Documentary Reveals the Untold Story of Yves Saint Laurent

Says his business and one-time romantic partner Pierre Bergé, "He invented the modern women's wardrobe."
Now six years after his death, a new biopic, Yves Saint Laurent in select cities nationwide, reveals more of the decadence behind the glamour.
Plagued by depression, Saint Laurent abused alcohol and cocaine for many years.
As he said at the time of his retirement in 2002, "I have been through sheer hell. I have known those fair-weather friends called tranquilizers and drugs ... but through it, I was able to rise to the heavens of creativity."
That's the legacy that Bergé, 83, wants people to remember.
"Yves often said the most beautiful clothes that can dress a woman are the arms of the man she loves," he says. "But for those who have not had the fortune of finding this happiness, I am there."
