Kristen Stewart's Balenciaga dress at the Met Gala wasn't on for long. The actress traded the frock for her favorite combo — a leather jacket, jeans, and a tee — before heading to an afterparty at the Top of the Standard. Earlier in the day, Kristen was seen rocking the jacket around NYC as well. Kristen attended the bash at the Metropolitan Museum of Art on the arm of Balenciaga's designer Nicolas Ghesquière. Her relationship with the brand is well established, and she's the latest face of their perfumes. Kristen also ventured to Paris earlier this year to check out Balenciaga's Fall 2012 show in March.
