Caviar and cigarettes? Well-versed in etiquette? Rami Malek and Lucy Boynton certainly looked aristocratic as they walked the Oscars red carpet covered in Cartier jewels. While the Bohemian Rhapsody co-stars have been quiet about their off-screen romance, they are no strangers to fashion. Malek and Boynton weren't afraid to show off their classic Hollywood style — particularly Boynton, who was a true killer queen in a plum off-the-shoulder gown with black velvet bow accents. Boynton accessorised the satin dress with Marilyn Monroe glamour waves, paired with a Cartier jewel ring and earrings that left her looking ready for a night at the opera.

Malek kept it classic in a custom three-piece black tuxedo from Saint Laurent by Anthony Vaccarello, accessorised with a Cartier watch and matching cufflinks. Even though he needed some help from Lady Gaga to fix his crooked tie, Malek truly captured the vintage Hollywood style as he accepted his Oscar for lead actor.
