Business owner, fashion designer and social entrepreneur Rachel Roy is a household name in the retail space. Her contemporary clothing fills the racks at department store giants like Nordstrom's and Macy's, with 250 points of sale as of 2017. She's also a member of the Council of Fashion Designers of America and penned the book, "Design Your Life."

But the entrepreneur is now taking on a different role — Roy has been tapped for a two-year ambassador position, dubbed Champion of Innovation, by UN Women. Roy will use her experience as a successful female entrepreneur to help with programs aimed at achieving gender equality and supporting female innovation and entrepreneurship.
