LOS ANGELES, United States (AFP) – 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 sashayed in a sheer black gown with a deep V neckline and long sleeves.

She wasn’t the only star to show some major cleavage.

Madonna channelled her inner naughty toreador in a skimpy black-and-pink Givenchy mini-dress, her breasts pushed up to a dangerous level. Thigh-high black boots and elbow-length gloves completed the look.

Rapper Nicki Minaj, up for two awards, 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.

Meghan Trainor, a nominee for record and song of the year for her sugary pop hit “All About That Bass,” strutted her stuff in a black dress with a long lace overlay. Her red carpet accessory? Her father.

Trainor said being at the Grammys was a “dream come true.”

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.

Two of the three sisters who make up the pop-rock group Haim — nominated for the coveted best new artist prize — turned up in basic black, but Danielle Haim strode down the carpet in a white pantsuit.

Britain’s Charli XCX — perhaps best known for singing the hook on Iggy Azalea’s ubiquitous hit “Fancy” — also worked the white suit look from Moschino, but gave it a girly twist with a pink bow tie.

Taylor Swift set herself apart in a blue-green Elie Saab gown with a high-low hemline.

Australian rapper Azalea also added a pop of color to the proceedings, in a royal blue figure-hugging Armani gown, with her blonde hair braided in a crown around her head.

The Grammys have been the scene of some of fashion’s classic red-carpet moments: Jennifer Lopez’s plunging barely there green Versace gown in 2000 is still a fierce benchmark.

The men of music headed into the Staples Center did not disappoint.

“It’s very, very surreal,” British singer Sam Smith — kitted out in white tie — told E! television when asked about his meteoric rise. Smith is a favorite to take home a few trophies, with six nominations.

Several of music’s top male stars went for shades of gray.

Pharrell Williams, who also has six nominations, busted out a pale gray Bermuda shorts suit from Adidas — but not the towering Vivienne Westwood Smokey the Bear hat that was the talk of last year’s show.

John Legend meanwhile opted for a gray Dolce & Gabbana suit with no tie.
