Rihanna’s Chopard Collection Dinner only had a handful of celebs in attendance, but the glamour was on high!

Check out the stylish trio of ensembles that took our breath away:

Rihanna was the belle of the ball in a Ralph & Russo Couture black gown that screamed elegance. Hot!

Winnie Harlow sizzled in an asymmetric shoulder cutout Roberto Cavalli design. She’s slaying at Cannes!

Julianne Moore beamed in a Sonia Rykiel number. She never disappoints.
