Scandalous! Taylor Swift pulled off a wardrobe change during her performance of her new single “I Knew You Were Trouble” at tonight's American Music Awards. She began in the flowing white sleeveless Ophira gown from evening wear designer Catherine Deane's Spring/Summer 2013 collection, only for her dancers to rip off the dress revealing a red corset and black tutu skirt, paired with a Jewelry by Nola vintage Chaplin rhinestone necklace with mixed gold chains, halfway through the song. These two looks off show off two very different sides of the 22-year-old—white, pure, typical Taylor and a more mature, feisty Taylor. Tell us: Which of her two looks do you prefer? Vote in the poll!
