Last night in Vegas, both music and fashion were at the forefront as celebs took to the red carpet for the annual Billboard Awards. Among the styled arrivals, we spotted Fergie in a bold, Hervé Léger cutout mini, while Nicole Kidman played a mix of casual glamour in an embellished Dolce & Gabbana and looser, side-swept braid. Meanwhile, Rihanna suited up in white-on-white Max Azria menswear, and Selena Gomez showed off a sultrier side in a cutout, black Dolce & Gabbana paired with red Giuseppe Zanotti heels. But it was Taylor Swift that brought the most glamorous of the night's looks, channeling old Hollywood in a sparkling Elie Saab gown, soft waves, and a bright red pout. Like most music award shows, this one brought a range of looks, now it's time to narrow it down to your favorite — which red carpet style is the standout?
