Country music's brightest stars invaded Las Vegas on Sunday for an evening of awards, however the true winner on the red carpet was the cut out trend. Between plunging necklines, sassy slits up to there, and bold slices, Faith Hill, Nancy O'Dell, Olivia Munn, andTaylor Swift were dressed to perfection. While Swift opted to take on three trends at once in her J.Mendelcrop top and skirt, she pulled it off with the ease and grace of a supermodel. (Perhaps it's thanks to all that time she's spending with Karlie Kloss?) Hill mastered the art of an aggressively low neckline in her powder blue Saint Laurent dress, understanding the need for balancing coverage with a v-neck that low. O'Dell brought variety to her one shoulder black dress by A.B.S by Allen Schwartz with cut outs accenting her waist while Munn's red Reem Acra afforded her a stunning moment on the carpet, supporting her country background as an Oklahoma native.
