Emma Stone!

Emma – forgo the traditional gown for pants instead. We're particularly fond of Emma's pick, a silver sequin bustier paired with bow-bedecked trousers (all custom Lanvin) and pointy-toe Christian Louboutin heels.

I love the color of her dark red hair, it's so striking against her fair skin. I think I had read that she is a natural blonde but I just can't picture that on her.
She went blond a few years ago and it wasn't as flattering. She looked so forgettable. The red brings out all her best features.
