The mega-stars of the music world rocked daring outfits in classic black and white on the Grammys red carpet Sunday, strutting their stuff in Los Angeles on the industry’s biggest night. Beyonce — who took home three Grammys — sashayed in a sheer black Proenza Schouler gown with a deep V neckline and long sleeves. Rapper Nicki Minaj left nothing to the imagination in a black Tom Ford gown that was cut down to her bellybutton in a wide V and hugged her hips. Pop princess Katy Perry, fresh off her well-received Super Bowl halftime show, rocked a sheer, white-silvery backless Zuhair Murad dress studded with crystals — and purple hair.
