Yeah yeah yeah

Christian Joy, infamous fashion designer for Karen O of the Yeah Yeah Yeahs, has launched her debut collection. For spring, the designer focused on easy-to-wear jersey T-shirt dresses, leggings and jumpsuits in graphic black-and-white. Though she's still planning to design stagewear for the Yeah Yeah Yeahs' next tour, the Brooklyn-based designer is moving on to more everyday designs. "I'm wanting to design clothes that I can wear, and challenging myself in a different way," Joy says. The spring collection was inspired by her youth growing up in Iowa with limited exposure to mainstream fashion. "I didn't pay too much attention to fashion growing up. My mom inspired me more than anything. She's a Christian but a hippie at the same time -- super D.I.Y." While you can purchase Joy's collection only at shops on the coasts, you can view it at www.christianjoy.us, modeled by none other than Karen O.

The collection is inspired by Giunta's background in painting and industrial design, and successfully straddles the line between fine art and commercial design.
