Emma Watson headed to the MTV Movie Awards tonight to present the trailer for her new flick The Perks of Being a Wallflower, which comes out September 14th. “Why do I always feel like I’m going to be sick before these things?!” she tweeted before she posed for cameras in a patterned halter-style dress by up-and-coming label BROOD by designer Serkan Sarier, a wide black cuff, and Tabitha Simmons strappy sandals. She also showed off her somewhat-longer strands, as she seems to be growing out her pixie from her post-Harry Potter days. How can she be nervous looking so fabulous?
