Times, they are a changin'. Yves Saint Laurent's newest campaign for spring '11 features latest It Girl Arizona Muse, who replaces YSL's previous model and industry favorite, Daria Werbowy. The campaign, shot by Inez van Lamsweerde and Vinoodh Matadin, was photographed in the gardens of Bled Roknine, a gorg beyond gorg '30s style villa in Marrakech. The villa itself was purchased in 1980 by Saint Laurent and his partner Pierre Bergé, making it a particularly sentimental nod to the late designer's cherished getaway. But with model-to-watch Arizona Muse as, umm, muse, there's also a heavy dose of the future, kind of like that dude who sells flat screens in the Riad.
