ALL BLACK: Stars including Catherine Deneuve, Alicia Keys, Isabelle Huppert and Katy Perry turned out for Stefano Pilati’s swan-song catwalk show for Yves Saint Laurent, which won the designer a standing ovation. Salma Hayek, accompanied by husband François-Henri Pinault, the chairman and chief executive officer of YSL’s parent company, PPR, clapped with her hands above her head. It was a good thing Rosario Dawson came dressed in black: The catwalk, which was plunged in darkness before the show, lit up to reveal an almost all-black collection. “We’re in Paris, so I always get on my good black here,” the actress grinned.
