Most elegant performance

Taylor Swift has at this point pretty much given up country music, right? The eleven-time AMA winner looked lovely as she took part in a Venetian masque-themed performance of her new song 'I Knew You Were Trouble,' which some have suggested was written about her ex, Jake Gyllenhaal. As for her mid-song costume change into a red bustier and puffy black skirt, that must have been magic because I literally looked away for a second and she was wearing something new!
