We're dying to know what Kate's wedding dress will look like, but the ensembles she's worn as a wedding guest might provide some clues about what she'll wear to her own.

In May of 2006, Kate attended her first wedding with the entire royal family—the marriage of Camilla Parker Bowles' daughter Laura to Harry Lopes. Kate wore a cream-colored brocade coat, but the real focal point of her look was her whimsical feathered hat. While it's nearly certain that Kate will wear a traditional tiara and veil for her wedding ceremony, perhaps she'll don a more festive chapeau for her reception.
