The first of Claudia Schiffer's ads for Yves Saint Laurent's spring/summer '09 campaign has come to light. As previously blogged, the supermodel replaces Naomi Campbell as the label's new face. The campaign, which was shot by Inez van Lamsweerde and Vinoodh Matadin, took Schiffer all the way up to the Hollywood Hills. Claudia steamed up the lens in this gorgeous YSL tuxedo jacket and long black skirt, against a giant 'Y' to reflect the campaig's 'Y's up' message. Stefano Pilati will also use the shots on YSL's manifesto, due out next Valentine's Day.
