Earth Day may be about a month away, but that doesn’t mean you can’t think eco-consciously today. Tonight, is teaming with Runway to Green, offering exclusive designer pieces from Balenciaga, Marc Jacobs, Jason Wu (left) and nearly 20 more immediately after they’re unveiled during a fashion show at the star-studded Christie’s Bid to Save the Earth Event in New York City. In addition, between 6 p.m. and midnight ET tonight, will donate 10 percent of proceeds from every item sold to Runway to Green, which benefits the Natural Resources Defense Council, Alliance for Climate Protection and United Nations Environment Programme’s Billion Tree Campaign.
