The 48th annual Academy of Country Music Awards provided the perfect "excuse" for a little Sunday night glamour, especially where Taylor Swift and Carrie Underwood were concerned. Both singers chose floor-length creations for the occasion, but that's where the similarities ended. Swift sparkled in a gold formfitting Dolce & Gabbana number, which also featured a bejeweled Art Deco-inspired neckline and a sexy low back. Underwood stuck to her red-carpet M.O. with a bright floral-printed strapless gown by Naeem Khan, coral chandelier earrings, and a black clutch. While they go head-to-head for Female Vocalist of the Year and Album of the Year at this year's ceremony, we're leaving it to you to decide who earned best-dressed status.
