Sarah Jessica Parker showed up to the at the Sex And The City 2 UK premiere with this hat or hair accessory. According to fashion journalist Jim Shi who I follow on Twitter Parker’s headpiece is by Irish born hat designer Philip Treacy. Based in London, Treacy has designed hats for Alexander McQueen’s white Haute Couture collection at Givenchy in Paris and for Karl Lagerfeld at Chanel. In 2009 he even designed a hat for Lady Gaga for the 2009 Grammy’s. I love the hat it’s a work of art and would love to wear it one day (I’m serious:)!
