Not only did country's biggest stars look fab on the Academy of Country Music Awards' red carpet last night, they also brought some serious style to the stage. Rihanna wore a fringed leather Versace dress during her duet with Sugarland's Jennifer Nettles, while Carrie Underwood slipped into a crystal corset, black tutu, and silk WTB bolero for her performance with Steven Tyler. And Miranda Lambert matched her glittery bustier Mandalay frock to her pink guitar. See more performance looks from Taylor Swift, Reba McEntire, and Martina McBride in the gallery!
