While Sarah Jessica Parker set cameras flashing in an Alexander McQueen gown and a wild Philip Treacy hat at last night’s London premiere of Sex and the City 2, costar Cynthia Nixon’s most prominent accessory for the evening was her noticeably longer hair. Just days after hitting the movie’s N.Y.C. premiere in a black Carolina Herrera with her signature shoulder-grazing bob, the strawberry blonde appeared last night in London with an extra several inches of wavy extensions framing her asymmetrical peacock-blue Narciso Rodriguez gown. We can’t remember ever seeing Cynthia with such long locks, and we love that she’s switching it up. Tell us: Do you like Cynthia Nixon’s longer hair?
