With stars including Rihanna and Cara Delevingne championing her fashion offering season after season, you can't blame Stella McCartney for ensuring her new season campaign is suitably chic and ultra-cool. The ethically minded British designer, who is known for her super-luxe and sport inspired collection, released a selection of images from her new Autumn / Winter 2013 campaign via social media sites, Facebook and Twitter, this week.

McCartney, who styled the campaign herself said, "This season I wanted to capture the spirit of the city an d the streets; an expression of urban life and real, everyday moments. We wanted to have a sense of fun and freedom, then contrast it with something slightly unexpected. There is a bit of surrealism, which may even be a bit strange."

What do you make of the shots?
