I was stunned when I saw the pictures of Emma Watson at the “Harry Potter And The Deathly Hallows Part 2″ World Premiere, which is taking place in Trafalgar Square, London tonight.

It’s a big budget movie, the world is watching so she opted to big, and they don’t come much bigger than an Oscar de la Renta ballgown.

I was expecting another mini dress, but she looked breath-taking wearing an Oscar de la Renta sand tulle sleeveless gown with embroidered bodice and full skirt from the Fall 2011 collection.

This choice was so unexpected that I’m totally wowed by it. She appears to be having an absolute blast on the red carpet.

Boodles jewelery completed her look.
