Meanwhile, fashion snapper Mario Sorrenti revealed he's working on a book of "mostly controversial" fashion images from the last 15 years.

On another front, YSL has signed a four-year contract to support New York's Metropolitan Opera. It will start with this season's opening night gala on April 21, a performance of Donizetti's "La Fille du Régiment" starring Natalie Dessay and Juan Diego Flórez. Designer Stefano Pilati and YSL chief executive Valérie Hermann will host the gala. The alliance marks one of YSL's biggest philanthropic endeavors and underscores its long time commitment to the classic arts.
