Rhapsody in blue!

As the mother of the bride, today's wedding of Prince William and Kate Middleton is a big day for the bride's mother Carole Middleton, too.

Not failing to impress, Middleton wore a sky blue wool crepe coatdress with matching satin piping and a matching day dress with pleated sleeves and pockets. Both pieces are by Catherine Walker, one of the late Princess Diana's favorite designers.

Mrs. Middleton's hat (also in the color scheme) is by Berkshire-based milliner Jane Corbett.
