Grabbing one of Carolina Herrera‘s designs just got a lot easier—and more charitable: At her spring 2013 show, the designer debuted the limited-edition T-shirt she designed for the Saks Fifth Avenue’s Key To The Cure campaign. “It’s a tree with a map of the world and all the little hearts inside the map,” she told InStyle.com. “I did the world because breast cancer goes everywhere in the world—it’s not only the United States or South America. It’s all over.” As if to underscore the global message, Spanish actress Penelope Cruz will serve as the Entertainment Industry Foundation’s ambassador for 2012. “Women should be safe,” Herrera said. “We all can be safe [with the right precautions]. We have the right to be.” The T-shirt, which retails for $35, goes on sale October 1st during the store’s annual charity shopping weekend—100 percent of the proceeds will be donated to the EIF’s Women’s Cancer Research Fund.
