Rihanna and Cara Delevingne both stunned at the Hollywood premiere of Valerian, but in their own individual ways. Rihanna went with a more girly/princess vibe, wearing a flowing Giambattista Valli gown. While Cara on the other hand, stuck with the theme of Sci-Fi movie and wore a sexy and futuristic look by Iris van Herpen (Fall 2017 Couture). I love both these looks equally and I can't wait to see what they wear for the many other premiere dates. And in case you were wondering, Rihanna's ribbon heels are from her Manolo Blahnik collaboration!
