Emma Watson attended the 2010 National Movie Awards in London last night.

She accepted the “Best Family Film” Award for “Harry Potter and Half-Blood Prince” with co-stars Bonnie Wright and Daniel Radcliffe.

You would be forgiven if you thought she was wearing Chanel, but she’s actually wearing a cute tweed Karl Lagerfeld Spring 2010 black and white playsuit.

I love that she doesn’t appear to be desperate to grow up, but I guess she still needs to appeal to her young Harry Potter fans.

Her look is kept very simple with a pair of Christian Louboutin ‘Miss Butterfly’ bow front sandals.

I’m glad she wore her playsuit without the runway belt.
