Portugal Colonial - Grammy red carpet: black and white, barely there and no ICE

Here are some key looks from the Crypto.com Arena:

- Black and white -

Author Truman Capote hosted a legendary Black and White Ball in New York in 1966 -- and the look is still a red carpet winner.

Puerto Rican megastar Bad Bunny -- already a double winner on the night -- dressed to impress in a Schiaparelli velvet tuxedo with a slightly fitted jacket and a white flower on his lapel.

Lady Gaga embraced her "Mayhem" era, rocking a high-necked sleeveless black feather gown from Matieres Fecales that trailed behind her in wisps of tulle. Her hair and eyebrows were bleached platinum.

K-pop singer Rose, a nominee for Record and Song of the Year for her ubiquitous banger "APT.," wore a Saint Laurent gown built from a black mini dress, and then topped with a billowing cream swath of fabric that created a skirt-like effect.

Britain's Olivia Dean, who won the award for Best New Artist, stunned fans in an elegant Chanel gown with a full white skirt and a black bodice with tiny spaghetti straps, adorned with sequins and feathers. Her hair cascaded down her back in curls.

- Plenty of skin -

Barely there sheer frocks have been on the runways since the start of the showbiz awards season, and Sunday night was no different.

Pop princess Sabrina Carpenter, who earned six nominations, is known for her glitzy showgirl style on stage, and she brought a bit of that sparkle to the red carpet, in a wispy Valentino gown with strategically placed floral appliques and rows of ruffles.

The members of girl group Katseye arrived in floor-length white Ludovic de Saint Sernin gowns, each with cutouts or revealing see-through lace.

Colombian singer Karol G wowed fashionistas with a sea foam green sheer dress that hugged her curves.

Chappell Roan, last year's winner for Best New Artist, perhaps took naked dressing too literally.

She removed a burgundy Mugler cape to reveal a wisp of a trailing skirt that was suspended from a pair of nipple rings, her body decorated with what looked like henna art.

- 'ICE OUT' -

Much like at the Golden Globes, a number of stars -- including legendary singer-songwriter Joni Mitchell -- wore "ICE OUT" pins to protest US President Donald Trump's sweeping crackdown by Immigration and Customs Enforcement agents.

Justin Bieber and his supermodel wife Hailey Bieber sported the pins as did singers Margo Price, Helen Shen and Jordan Tyson.
