Billboard Music Awards 2013: Black And White, And Black-And-White

The 2013 Billboard Music Awards blue carpet was teeming with sexy, stylish celebrity guests. Being that it was in Las Vegas, we expected lots of glitter and skintight silhouettes, but we were pleasantly surprised. The looks were refreshingly high-fashion in striking black, white or a combination thereof.

As for the ladies who went dark, Emmy Rossum was gorgeous in a long-sleeved black Zuhair Murad gown with mesh and swiss dot panels, while Ke$ha shocked us in a different way than usual. From her natural makeup and unfussy hair to her simple, chic Givenchy and Palladium outfit, she underwent a major makeunder.

Hayden Panettiere was sophisticated in a halter-neck black gown with Old Hollywood hair, and Jenny McCartney showed off her rock 'n' roll side in a low-cut tank, lots of chunky jewelry, and a sliced-up skirt.

Jennifer Morrison played with proportions in a bodysuit with sheer overlay by Kristian Aadnevik.

Alyssa Milano was a vision in a white Emilio Pucci outfit. An embroidered one-shouldered tunic over sheer, wide-leg pants created a dramatic look. And Selena Gomez was high-impact in a neon-accented cut-out white gown by Atelier Versace.

Kimberly Perry from The Band Perry went full-on glamour in a jewel-top, princess-skirt gown.

Nayer wore an, um, interesting ensemble consisting of a black-and-white printed jumpsuit with an open top and a hood. She also brought her dog.

Rounding out the list -- in the most amazing look of the night -- was Miley Cyrus in a Balmain diamond-checked and lace-embroidered one-piece. With her slicked-back hair and matte red lipstick, she was flawless.
