Celebrity-fronted fragrance campaigns are having a big moment. Last week, Balenciaga dropped a colorful advertisement for its Florabotanica scent starring Kristen Stewart in a floral look by the brand. Shortly after, Gucci teased Blake Lively's short film for its Gucci Premiere perfume with a glossy image of the Gossip Girl star in an open-back gown. Lively's fashion film, from Drive director Nicolas Winding Refn, will premiere at the Venice Film Festival September 1st. We can't wait to see the film—and smell the scents!
