Rashida Jones & Theory's New Stylecause

Known she-crush Rashida Jones has already made a name for herself as the star of Parks and Recreation, I Love You, Man, viral videos on Funny or Die and, as if those efforts weren't enough, she's a Harvard-educated humanitarian (hence the she-crush). Now, Jones has teamed up with another current favorite, clothing line Theory, to lend a hand with their new Fashion Insider project and help support two of her favorite causes in the process.

Fashion Insider is part of Theory's new spring 2010 campaign. They invited 17 of today's hottest stylists to pour over lookbooks and create outfits based on the spring collection, choosing their must-have pieces in the process. Stylecause is a further extension of the Fashion Insider campaign — think of it as Fashion Insider with a do-good component (insert Tonic seal of approval here, here, and here).

According to the release, "Through Fashion Insider: Stylecause, Theory will invite members of the entertainment community to join the Fashion Insider team to style for a cause. Each will mix, match and style their must-have Theory looks to raise much needed funds. Ten percent of the proceeds from the sale of the items in each outfit will be donated to the selected charity." Enter Rashida Jones, inaugural celebrity guest stylist for Theory's Fashion Insider: Stylecause.

Jones has used her fashion savvy to style three summer looks that will be sold exclusively at Theory retail stores and Theory.com beginning on April 22. Ten percent of proceeds from all sales will go directly to two organizations the actress supports. "I'm delighted to be working with Theory on such a wonderful project that benefits two organizations so clearly dedicated to young people — Peace First and Children Mending Hearts,” Jones says on the campaign website.

Both Peace First and Children Mending Hearts work to help risk-averse youth and combat the skyrocketing youth homicide rate through support groups and in-school programs. Peace First works with schools to build safer climates and they rely on young adult volunteers to teach students how to become active, engaged citizens. Children Mending Hearts is a global arts exchange program between children living in conflict zones abroad and at-risk children in America. It is overseen by a team of arts and culture specialists who conduct workshops to help the children find their inner voices and creativity.
