The new black-and-white ads were shot by husband-and-wife team Inez van Lamsweerde and Vinoodh Matadin, while YSL designer Stefano Pilati played creative director.
Werbowy, who is also the face of Lancôme, was shot on the spiraling staircase inside the Hôtel de Clermont-Tonnerre, which is the Paris headquarters of Artemis, the holding company for Yves Saint Laurent parent PPR.
In the first images revealed, Werbowy wears two of the severely cut black frocks from the nearly all black-and-white Fall 2010 collection, believed to be inspired by nuns, although Pilati calls it an homage to the early work of Saint Laurent himself combined with the idea of protection.
Werbowy, in a jet-black bobbed wig, is accessorized with dark leather gloves, a floppy black hat, platform heels with spiky horsehair trim, and a long chain necklace with a New Look silhouette pendant.
Be on the lookout for the rest of the ads in the August 2010 issues of your favorite fashion glossies around the globe.
In the meantime, see how this campaign measures up against the Fall 2010 ads of Louis Vuitton and Calvin Klein.
