As part of their "Fashion Insider" campaign, Theory's "Stylecause" invites members of the entertainment community to put their style savvy to use for a good cause by mixing and matching must-have Theory looks to help raise funds for charity.

Rashida Jones (NBC's "Parks and Recreation") recently styled three summer looks now available at Theory retail stores and on Theory.com; 10% of the sales proceeds from any of the items in her looks will go to Peace First and Children Mending Hearts, two wonderful organizations dedicated to educating and empowering at-risk children everywhere. “I'm delighted to be working with Theory on such a wonderful project that benefits two organizations so clearly dedicated to young people,” says Jones.
