Oscar-winning actress and Lancôme ambassador Kate Winslet teamed-up with the cosmetic brand to create a special three-product line to benefit her new Golden Hat Foundation. After seeing an Icelandic documentary about autism, Winslet was moved to start the the charity to better the lives of children living with the disorder. (The hat concept was inspired by a poem written by a child who has autism.) "I walked away from the experience unable to let it go," she told InStyle exclusively. But creating the charity was just a start. She's also supporting it with her work. This April, Winslet will publish The Golden Hat: Talking Back to Autism ($20, amazon.com), a series of celebrity self-portraits and inspirational words. And this holiday season, she collaborated on Lancôme's Golden Hat collection, which directly benefits the charity. "I took the idea to Lancôme and they said, 'Let's absolutely do it,'" Winslet said. "They’re very passionate about the charities they support." Click "See the Photos" to check-out the gorgeous pieces and hear what Winslet loves about each one.
