Emma Watson haircut last year.
Emma Watson bedazzled in two winning looks at the world premiere of "Harry Potter and the Deathly Hallows : Part 2" in London on Thursday.

Emma Watson, now 21, went teary eyed at the event while she bids goodbye to the most success franchise and novel adoptation. Watson was first greeted by fans on the red carpet in a tulle Oscar de la Renta floor-length gown, which featured a sheer neckline and embellished bodice.

Later, Emma Watson added a little edge to the evening look by topping her dress with a white, grazed blazer.

For the premiere after party, Watson slipped into a cream and textured Elie Saab frock from the label's spring summer 2011 couture collection. She paired her ensemble with matching peep-toe pumps and minimal jewelry.
