Just because something is designer, doesn’t make it cute! Karlie Kloss flopped on the red carpet at the Cannes Film Festival in a lace Valentino dress, but we love that she shared behind-the-scenes pics with her Instagram followers! Blake Lively stole the show in a burgundy Gucci dress and Jane Fonda stunned in a similar color gown by Elie Saab. Other stars that caught our eye include: Kendall Jenner, Nicole Kidman and Zoe Saldana. Check out our best and worst looks from the festival right here!
