If postal ninjas waylaid your invitation to one of the biggest eco-fashion shindigs this year, don’t worry your pretty head: “Runway to Green” will be streaming live at 8:30 p.m. ET on Vogue.com. All looks from the 26 participating fashion designers (including Stella McCartney, Balenciaga’s Nicolas Ghesquière, and Thakoon Panichgul) will go on sale at Net-a-Porter directly after the show, with proceeds benefiting the National Defense Resources Council and the Central Park Conservatory. Plus, Jill Fehrenbacher, our editor-in-chief, will be on hand to rub shoulders with the likes of Alexander Wang, Michael Kors, and Saturday Night Live’s Seth Meyers, while our intrepid videographer, Brit Liggett, will be stalking the green carpet to spill the deets on any off-camera action.
