Rihanna Cannes Ralph Russo black gown, Chopard diamond earrings, watch and rings, Giuseppe Zanotti suede mules, Roger Vivier flower crystal envelope clutchRihanna attended a party tonight at the Cannes Film Festival in honour of her collaboration with Chopard. The superstar designed two Rihanna Loves Chopard collections with Caroline Scheufele, the brand’s co-president and creative director. The first collection is up for pre-order right now while the Cannes dinner marked the launch of the Haute Joaillerie collection. These more glamorous pieces are perfect for red carpet events. Mel Ottenberg styled Rihanna for this red carpet and his assistant provided the details on the look. The black strapless silk gown and tulle shawl are custom Ralph & Russo.

Rihanna’s jewellery is all Chopard, of course, and among the amazing pieces are a pair of diamond transformer earrings and a watch from the Rihanna Loves Chopard high jewellery collection. The prices are available upon request.

The Barbadian accessorised her look with a Roger Vivier handbag. The envelope shoulder bag doubles as a clutch and features flower-shaped crystal detail. Purchase from MyTheresa or Luisa via Roma for $1,675. Finally, her suede and Swarovski crystal mules are custom Giuseppe Zanotti sandals.
