She's more typically seen in a rather racy ensembles, particularly when performing on stage. But Rihanna opted for a more demure look as she attended a dinner celebrating the launch of her collaboration with Chopard in Cannes on Thursday night.
The singer, 29, exuded old-school Hollywood glamour in a black tulle gown by Ralph & Russo as she arrived at the star-studded event.
Covering her shoulders with a sheer shawl, she accessorised the 1950s-inspired look with a chic clutch bag featuring a silver clasp.
Rihanna no doubt chose a black gown in order to ensure that her jewellery stood out, opting for an elegant diamond choker and matching earrings, as well as a dazzling watch on her wrist.
Wearing her lengthy tresses in an elegant up' do, she added a pop of colour with a bold red lipstick, before adding lashings of mascara to finish.
