Bold shades, bright whites and dazzling metallics were the order of the day as stars arrived on the red carpet at the 90th Academy Awards.

The multi-coloured swathe of gowns at the awards ceremony marked a change from the Golden Globes and the Bafta Film Awards, which saw stars wearing black in solidarity with anti-sexual harassment campaigns #MeToo and Time’s Up.

Leading the pack in the style stakes were Oscar nominees Margot Robbie, Saoirse Ronan and Sally Hawkins, each sporting very different gowns at the prestigious event.

I, Tonya star Robbie was one of the many celebrities who opted for white on the night.

The best actress nominee’s gown was cut in a strapless style with a draped, glittering sash across the front and shoulders.

Jennifer Garner wore one of the most eye-catching pieces of the night: a royal blue dress with a full skirt, asymmetric neckline and a long train that trailed behind her as she walked the red carpet.

There were even more colourful looks from Nicole Kidman, whose midnight blue dress included an exaggerated peplum detail on the hips and a thigh-high split on the skirt, and best director nominee Greta Gerwig, who brought summer to the ceremony in a floral yellow frock.

Salma Hayek and Ashley Judd went for power purple dresses, while Whoopi Goldberg – clad in a turquoise, yellow and purple floral-printed gown – wore one of the few multi-coloured dresses.

There was plenty of white at the ceremony, with best actor nominee Timothee Chalamet looking striking in a white tuxedo, and Laura Dern in a figure-hugging dress with an oversized detail on the shoulder.

Although the majority of stars at the Oscars were not clad in black as at the previous ceremonies, some were sporting Time’s Up pins.
