While celebs like Katy Perry and Cara Delevingne were rocking rainbow styles at Burning Man, Dakota Fanning (who has been giving us serious style inspo as of late with her rose gold sunnies) was busy slaying the red carpet at the Venice Film Festival in a sequined Miu Miu number that was fit for a mermaid.

On hand to promote her new film, Brimstone, all eyes were on the starlet as she swept down the carpet in the light blue holographic sequined gown, and we can鈥檛 say we blame them!

The dress was so gorgeous, in fact, that Dakota herself couldn鈥檛 keep her hands off it.
