Another week full of glamour from the Cannes croisette is what our new Best Dressed list is all about. While we love award season, Cannes always takes the cake when it comes to grand red carpet fashion. This festival above all is where you go big, or go home. And go big, is exactly what these stylish ladies did. Landing at our #1 spot this week is teen queen Elle Fanning. Elle always makes interesting choices when it comes to what she wears, and this dazzling Zuhair Murad ballgown was no exception. The intricate beading and feminine floral applique makes this dress fit for a princess. A Cannes princess at that. No surprise momma-to-be Blake Lively continued to blow us away. The L'oreal spokeslady gave us the best case of the blues in a vibrant, bump hugging Atelier Versace number. Blake puts an all new spin on A+ maternity style. The always stunning Charlize Theron left her gown at home and instead opted for a chic menswear inspired ensemble. We always love an unexpected, well executed androgynous look and no one pulls off effortless chic quite like the Dior muse. Katy Perry delivered a floral explosion in a breathtaking Marchesa piece. For most people this might have been too much dress, but Katy pulled it off without a hitch.
