Mulberry hosted a glamourous party in London to celebrate the British label's Spring 2012 collection. The ballroom at Claridge's was packed full of arcade games and other retro treats (eight foot tall ice-cream cones!) designed to bring back those carefree days of youth. All the cool kids were there. Kristen Stewart and Harley Viera Newton rubbed elbows with the likes of Erin O'Connor, Jade Williams and Tali Lennox (spotted here carrying the small Bayswater bag).
