Hedi Slimane's Saint Laurent unveils its latest rock 'n' roll-inspired venture with a lookbook for the aptly-named "Psych Rock" collection of men's and women's ready-to-wear. Shot in the Parisian house's signature black-and-white style and donned by a crew of street-cast models, the collection takes a decidedly more bohemian, psychedelic lean (hardly surprising given the name) than the label's usual fare and is available now from the Saint Laurent webstore.

If that's all a bit too much of a departure from the label's classic chic, then we'd suggest heading over to the first and second lookbooks for their altogether more tame "Permanent Collection."
