Dakota Fanning gave us a true fairy-tale moment on tonight's Met Gala red carpet. The actress showed her sweet style sensibility in a princess-worthy, lavender Louis Vuitton gown. The confection spoke perfectly to her youth with soft textured rosettes and a romantic off-the-shoulder neckline. Her accessories were equally feminine, comprising a glittering bracelet and flower barrettes tucked into either side of her hair. We love that Dakota mirrored her gown's dreamy hue with a metallic lilac manicure and coordinating box clutch. What do you think of the actress's glamorous arrival?
