Elle Fanning wore an eye-catching karate-inspired outfit with open toe sandals and socks with pictures of hotdogs on them while out and about at the 'Sundance Film Festival'! The 15 year old actress was spotted in an all denim karate outfit with an actual black belt as she was promoting her new film the 'Young Ones'. However it was her socks that stole the show with pictures of hotdogs on them with mustard and ketchup! Later on she put on a denim jacket as the temperatures dropped in the winter town.
