Hedi Slimane, creative director of Saint Laurent, recently tapped the beautiful singer/actress Sky Ferreira to model in ads for the Pre-Fall 2013 collection. Sky's impossibly cool attitude meets Slimane's sharp, monochrome photography to yield excellent results. In every shot, Sky makes the collection covetable and contemporary. It's nice to see these two collaborate again, after Sky was his muse in 2011. Slimane also shot her latest EP cover.
