Emma Watson took her new hair do for a test drive at the launch of the official countdown to “Harry Potter and the Deathly Hallows Part 1″ today.

In 100 days time – November 19 – the first part of the last installment of Harry Porter will hit the big screen.

Emma looked adorable wearing a lace long sleeved Alice by Temperley playsuit with black pumps.

I wanted to judge her hair again on the red carpet when she’s had a chance to dress up, and the crop still gets the thumbs up from me.

She carries the look with amazing confidence.
