Kristen Stewart  looked stunning in a sultry crimson Proenza Schouler  gown, which managed to stand out even on the red carpet, at tonight's Met Gala in NYC. She pulled back her hair to expose her back in the gown, which kept her pretty covered up in the front, although it also gives a peek at her leg from the side.
