Gwyneth Paltrow and a handful of other celebs with enviable wardrobes have decided to do a little spring closet cleaning—and all of us can get in on it! Stars including Beyoncé, Nicole Richie, Miranda Kerr, Kate Hudson, and, of course, G.P. have donated some of their barely worn designer goods for Goop’s annual closet sale, including Queen Bey’s custom-made multicolor Stuart Weitzman boots from her Mrs. Carter Show World Tour or Christian Louboutins from the Candidly Nicole star’s closet. The best part is 100 percent of the proceeds will go to DonorsChoose.org, a charity that gives classroom supplies to public school teachers. Many items have already sold out, but there are still a handful left. Our advice? Head over there fast, before it’s all gone.
