Music's brightest stars bared lots of skin at the Grammys in Los Angeles on Sunday, oozing sex appeal and taking fashion risks on the industry's biggest night. Beyonce, who opened the show with a sultry performance of "Drunk in Love" with her husband Jay-Z, smoldered in a curve-hugging white mesh Michael Costello gown with strategically placed flowers, leaving little to the imagination. Taylor Swift, who was nominated for Album of the Year but lost out to Daft Punk, glittered in a metallic belted short-sleeved golden Gucci gown with a daring slit up the back, and her hair in a simple ponytail. Pop princess Katy Perry, who had two nominations for her girl power anthem "Roar," floated up the red carpet in a gauzy white Valentino number, with music notes playfully scattered along the skirt.
