Kristen Stewart posed on her way into Mulberry's London Fashion Week afterparty last night. She changed into denim and a sweater for the festivities after donning a dress to sit front row to see the collection earlier in the evening. Kristen Stewart and Kate Moss were seated together at the show, and Kristen showed off her long, darker hairstyle that she later twisted into a side braid. The new 'do is for Kristen's Snow White character, which she took a break from to attend the fashion fun. She's been filming the movie in the UK for the past few months and got a sweet visit from boyfriend Robert Pattinson before he returned to LA just last week. Rob made it back to the West Coast just in time for the Emmys, and though he didn't attend the show, Rob was spotted at Jimmy Fallon's afterparty at Trousdale.
