Emma Watson Keeps It Simple In New York

Last night was the New York premiere of Harry Potter and the Deathly Hallows Part 1 where Emma Watson proved she is no longer little Harmione Granger.

The 20 year old looked all grown up in a sleek black Calvin Klein Collection dress and matching metallic CK heels.

We liked her fun feathery Rafael Lopez world premiere dress better.

This is a little too mature for someone her age, not to mention boring.

What do U think???
