Grammys newcomer Sam Smith looked dapper in a white bow tie and Madonna rocked one of the season's most eclectic red carpets Sunday in a bedazzled two-corner black hat, burlesque-esque corset look with matching thigh high boots.

Madonna's big-shouldered shorty outfit was custom Givenchy couture by Riccardo Tisci. She wore not much underneath, flashing a black thong and fishnets at the Staples Center in Los Angeles. She wasn't a hit with some in the Twitter peanut gallery: "Just got a glimpse of Madonna arriving. Seems to be channeling some mix of the Duchess of Windsor and Mae West," one chimed in.

Beyonce and Miley Cyrus went for black -- Cyrus in strategic, sexy cutouts and the queen in a low-V neck embellished look with a train from Proenza Schouler.

Audacious singer-actress Joy Villa was encaged in revealing bright orange, and it was unclear how Sia could see under her huge shaggy white wig.

Brandy Clark showed off a killer pair of metallic silver Prada pumps under a sparkly, second-skin silver-and-black gown, while Nick Jonas chatted hands in pockets of a light gray tweed suit with a touch of yellow and ultra-skinny trousers.

How's Clark handling newfound fame and regular everyday life? "Squeeze myself into this dress, for starters," she told The Associated Press.

Ariana Grande had her signature high ponytail in place, wearing a white and silver, one-shoulder Versace with a cut out back -- Big Sean by her side. "I'm wearing Saint Laurent man, head to toe," he added of his shades of black tuxedo.
