Oscars red carpet: Jessie Buckley, Rose Byrne and Amy Madigan steal the show at 98th Academy Awards

Rose Byrne was one of the first celebrities to walk the red carpet at the 98th Academy Awards.

The Australian actress, who is nominated for best leading actress for her role in If I Had Legs I'd Kick You, wore a strapless black fishtail gown by Dior, with floral embroidery across the bodice and hem.

Byrne paired the look with slicked back hair, a statement necklace and a bright red lip.

Jessie Buckley stole the limelight at the 98th Academy Awards in Los Angeles, completing her awards' season clean sweep, after being crowned best actress.

Dressed by stylist Danielle Goldberg, Buckley donned a pink-and-red Chanel gown designed by Matthieu Blazy as she took to the red carpet.

Up-and-coming actress Chase Infiniti, who appeared in Paul Thomas Anderson's film One Battle After Another, chose springtime hues for her pale purple gown by French fashion house Louis Vuitton.

The form-fitting bodice was accentuated by a billowing ruffled skirt, and Infiniti kept her look relaxed with her micro braids left loose.

Also opting for colour on the carpet was Norwegian actress Renate Reinsve, nominated for the best actress award for her role in Sentimental Value.

Reinsve also wore a Louis Vuitton creation: a vivid red strapless dress with an asymmetric hem. She leaned into the minimalism of the look with simple, slicked back hair, no necklace and strappy sandals.

The Brutalist star Felicity Jones wore a pale lemon gown to walk the red carpet, with a tulle-caped skirt overlaid and delicate sequin detailing.

Opting for a monochromatic look was Clueless actress Alicia Silverstone, who wore a custom Christian Siriano outfit, which included a black velvet strapless bodice, matching gloves and a sequinned white skirt.

Bridgerton star Charithra Chandran wore a rich emerald gown by Miss Sohee on the red carpet. The satin strapless look included a bow detailing on the rear and a voluminous skirt.

Lola Kirke, who appears in the record-breaking film Sinners, which has clocked up a total of 16 nominations at this year's Oscars, wore a whimsical black midi-length dress with bow detailing, lace and sheer panels.

Hamnet author Maggie O'Farrell, whose award-winning novel has been given the big-screen treatment, wore a bright fuchsia gown for the Oscars.

She accessorised her look with black accents in the form of a belt, necklace, lace gloves and fascinator.
