Dakota Fanning Is a Glittery Stella McCartney Mermaid at Now Is Good Premiere

In her new flick, Dakota Fanning plays a girl dying of leukemia, and on the red carpet she plays a girl wowing us with a sparkly gown.

If this is what 18 looks like in Hollywood, we wish Dakota Fanning could stay like this forever.

Check out the child star, now all grown up in a glamorous Stella McCartney gown at the premiere of her latest film, Now Is Good, in London.

She left her hair down in a nod to her youthful age, but that dress, along with a set of sophisticated Jimmy Choo sandals, clearly signaled that Fanning is ready for leading lady status.

She's already started to take on more complex fare—Now Is Good is about a girl with leukemia who hopes to lose her virginity before she dies.

The Daily Mail has weighed in on this look, too, declaring the Twilight vampire, "pale and interesting." We prefer, "an ivory tower of glitz," but whatever. Point is, we like it, we want to see more of it, and we hope that Dakota keeps this stylist on speed-dial!
