Rich jewel tones and sumptuous velvet gowns were favourites on the night, with Lady Gaga wearing a custom emerald green Ralph Lauren Collection gown, which took 150 hours to make according to the brand.
Director and actress Emerald Fennell donned a royal blue velvet Gucci tuxedo for the occasion, paired with gold platform heels, while Hayek wore a purple velvet Gucci gown.
Both Campbell and Belfast star Caitriona Balfe wore black velvet gowns. The English supermodel's was a Burberry design, while the Irish actress opted for an Armani Prive piece.
The men of Hollywood also turned out in style, with Riz Ahmed, Daniel Kaluuya and Sebastian Stan all putting in an impressive effort on the red carpet.
Ahmed wore a Gucci tuxedo in clashing hues, with a dusty blue jacket, pale pink shirt, brown trousers and a black mohair vest. Stan looked sharp in a Givenchy tuxedo elevated with an embellished collar.
Kaluuya, however, pulled out all the stops in a Prada coat, finished with vibrant blue feather cuffs and trimming.

Jane Campion was named best director for The Power of the Dog, becoming only the third woman to win the prize in the 75-year history of the awards.
Lead acting trophies went to Hollywood star Will Smith and British performer Joanna Scanlan. As an event that has worked to overcome a lack of diversity, the Baftas this year recognised a wide rage of talents, including the first deaf winner, American actor Troy Kotsur, for his role in Coda.
British film academy chairman Krishnendu Majumdar opened the show, which was hosted by Australian actor-comedian Rebel Wilson, with a message of support for Ukraine.
