Designers and celebrities walked a green carpet at Christie’s Auction House in New York last night to take part in a Runway to Green fashion show. The event featured looks from 29 designers, including Prada, Balenciaga, Marc Jacobs and Alexander McQueen. Pieces from the show are currently available on Net-a-Porter.com, and at least 10 percent of the sales from each item in the Runway to Green Collection will benefit the Alliance for Climate Protection, the Natural Resource Defense Council and the United Nations Environmental Program’s Billion Tree Campaign.
