Even when Rihanna tones it down, she still looks pretty amazing.

The 29-year-old singer was the guest of honor at the Chopard dinner on Thursday -- held in honor of her new collection with the iconic brand -- during the 70th annual Cannes Film Festival in France. Rihanna chose a chic, floor-length black Ralph & Russo gown for the occasion, and wore a matching sheer shawl. Elegant Chopard jewelry and bright red lipstick completed her simple, yet super glamorous, look.
