Laura Parker-Bowles and Harry Lopes Wedding, May 2006
In a clear sign that things were getting serious between Kate and William, she attended his stepsister's wedding, along with Prince Charles. Kate was cool and crisp in a cream Day Birger et Mikkelsen brocade coat and a cream and brown feather fascinator, while the dress underneath was a thigh-skimming champagne lace Collette Dinnigan.
