Fashion brand Saint Laurent unveil their 2015 Permanent and Pre-Fall women’s wear collection featuring model Helena Severin. Maintaining Hedi Slimane’s signature black and white style of photography, the new collection culture clashes 70s glamour and rock and roll chic, with pieces including black, leather collar shirts, silk schoolgirl blouses, zip mini skirts and leopard woven mohair sweaters. The campaign was shot back in January of this year in Los Angeles.
