Oscars red carpet: Stars and fashion in pictures

If the Oscars gave out an award for best dressed, it would be the most hotly contested prize of the night.

Hollywood's biggest stars are turning on the style as they walk the red carpet for the glittering ceremony in Los Angeles on Sunday.

They included One Battle After Another's Chase Infiniti (below), who has announced herself as both a major actress and a fashion icon this year, wore a lavender custom Louis Vuitton gown.

Rose Byrne (below), nominated for If I Had Legs I'd Kick You, wore a black custom Dior dress embroidered with an intricate floral pattern.

Norwegian actress Renate Reinsve, nominated for Sentimental Value, has favoured Louis Vuitton throughout her awards season campaign. For the Oscars, she wore a simple yet striking custom red Louis Vuitton dress by Nicolas Ghesquiere.

Bella Thorne decided to go with a softer touch in black feathered cuffs and a sheer slip.

Hamnet author Maggie O'Farrell, who is nominated for co-writing the screenplay for the film adaptation, opted for a bubblegum pink gown with black lace gloves and mesh fascinator hat.

Ballet star Misty Copeland's monochrome outfit featured a playful tutu. She will dance on stage at the ceremony during the performance of the nominated song from Sinners.

British actress Felicity Jones, who is in best picture nominee Train Dreams, picked pale yellow Prada.

Hudson Williams may not have been nominated at the Oscars, but he has been one of the most notable breakthrough actors of the past year, thanks to his role in TV series Heated Rivalry - the viral hit about two ice hockey players who fall in love.

Songwriter Diane Warren, who is nominated for best original song and is hoping for 17th time lucky at the Oscars, wore an elegant satin suit topped off with a black neck bow.

Amelia Dimoldenberg, who has returned to the Academy Awards as red carpet reporter and social media ambassador for the third year in a row, wore a sculptural black Ralph Lauren column gown, Jimmy Choo shoes and Bvlgari jewellery.
