Diane Von Furstenberg, Proenza Schouler, Alexander Wang, Rag & Bone, Narciso Rodriguez, and more have designed outfits inspired by the peace sign to celebrate its 50th anniversary. The designs — all made from sustainable materials, natch — were commissioned by environmental nonprofit Earth Pledge. They'll debut in the Barneys' holiday windows on November 16, which are themselves inspired by Tom Brokaw's book, Boom! Voices of the Sixties: Personal Reflections on the '60s and Today. Additionally, 5 percent of sales on November 16 will benefit Earth Pledge. We have a peek at the designer creations in the slideshow.
