'Barbie' lost most of its Oscars, but its cast won the red carpet

Robbie arrived at the Oscars in a strapless black dress from Versace. The gown ruched at the waist before flowing to the floor and was covered in sparkles, adding dimension to the simple silhouette.

Robbie also kept her jewelry simple, only adding a chunky bracelet and ring to the look.

The dress was a departure from Robbie's "Barbie" style, which has mostly been pink and inspired by real Mattel dolls.

Ferrera's Versace dress had a simple form-fitting silhouette with a square neckline that fell into a delicate point, thick straps, and a subtle train.

The dress was covered in pink sequins, sparkling as Ferrera walked the red carpet. A choker completed the playful look.

The draped gown had a Grecian silhouette, with the neckline plunging to the waist and a thigh-high slit cutting up the skirt.

Rae accessorized her look with strappy heels and a clutch.

Gosling chose an all-black Gucci look for the Academy Awards. His shirt, which he wore unbuttoned to nearly his navel, and jacket were lined with sparkly silver trim, giving the look a touch of glamour.

A simple necklace and pink socks, which peeked out from his pants as he walked, completed his chic ensemble.

His jacket and trousers were covered in hand-embroidered crystals, and he wore a solid pink shirt underneath.

To complete the stage outfit, the actor sported pink socks, custom pink leather gloves, black Gucci sunglasses, and shining dress shoes.

Gucci designed her golden gown, which sparkled in the light and was lined with small crystals along its neckline. It had a form-fitting bodice and a long skirt that reached the floor.

Gerwig wore a statement diamond choker with a pear-shaped pendant to complement its shimmering fabric.

Fendi designed Liu's suit, which he wore with no shirt.

The asymmetrical jacket buttoned at his waist with a silver brooch, and his pants had a subtle flare.

McKinnon didn't wear a shirt with her double-breasted jacket, calling attention to the sparkly necklace she used to accessorize her look.

Flared pants and pointed-toe heels tied the look together.

The actor's black tuxedo had a slight sheen on the lapel, so it stood out as he walked the red carpet.

He accessorized his outfit with a black bow tie and shoes that featured a statement buckle.
