SHOWstudio: The Daphne Guinness Collection

To honor the late Isabella Blow, Daphne Guinness has set up a foundation to support aspiring art and fashion students and to facilitate further research into depression and mental health. Nick Knight speaks to Guinness about the objectives behind this and her Christie's auction taking place 27 June 2012, which will sell treasured pieces from her archive, including Alexander McQueen and Balenciaga.
