Need a little pick-me-up at the end of a long day? Check out this amazing video that we spotted over at Strollerderby—an impressive one-woman medley of Disney tunes that is guaranteed to make you smile. Apart from having an amazing voice, we love singer Heather Traska‘s fun costumes—according to her YouTube page, there are 30+ characters/looks throughout the video, all styled by Traska herself. Can you believe she’s only 17 years old? We bet we’ll be seeing her debut album very soon!
