Are hats back? Sarah Jessica Parker wore a hat at the world premiere in London of the Sex and the City movie scheduled for U.S. release on May 30. And what a hat! The vertical green creation, which featured a large flower and butterfies among smaller flowers, easily added several inches to the petite star's height. British millinery designer Philip Treacy, known for his flamboyant creations, designed the hat, which coordinated with Sarah Jessica Parker's green dress by Alexander McQueen. Who says fashion isn't fun?
