Anne Hathaway  has changed up her look many times at the Met Gala, and the 2014 red carpet ensemble on Monday night at the Metropolitan Museum of Art's Anna Wintour Costume Center was no different. After wearing Valentino  two years in a row, Anne went red in Calvin Klein . In 2013, the actress memorably debuted a platinum blond 'do, but she didn't make quite as bold of an entrance this year. However, she has come a long way from her long hair and purple Marc Jacobs  gown at her first appearance in 2009.
