Taylor Swift [1] is known for her epic dance moves [2], and the singer didn't disappoint at the Academy of Country Music Awards in Arlington, TX, on Sunday. Channeling a Southern belle, Taylor revealed just enough skin in a blue Reem Acra dress. Although the outfit looked more for a ball and less for a dance party, Taylor still managed to bust some serious moves in the audience during performances. Dancing aside, it was still a big night for the star, whose mom, Andrea Swift, delivered a touching tribute [3] in her honor. The speech came less than two weeks after Taylor shared news of her mom's cancer diagnosis [4] in a heartfelt letter. Read on to see Taylor put a smile on her face with some fun dancing.
