Celebrity women wearing a special edition pink Planned Parenthood shirt began proliferating on Lena Dunham’s Instagram feed Thursday morning. Earlier this month, the organization paired up with the actress, director, and new author on her book tour for Not That Kind of Girl. On Thursday, Dunham premiered a limited-time Planned Parenthood shirt, complete with her signature, the proceeds of which will go towards the Planned Parenthood Action Fund. So proud and pleased to share the official shirt of my book tour, on sale to benefit @PPact!
