What is it about these female Royals that they can't keep their tops on? Princess Diana was photographed topless on a yacht; Sarah, Duchess of York has been snapped topless and sucking a toe; Prince Edward's wife, Sophie (Duchess of Wessex) has been immortalized topless. And now Kate. Diana topless wasn't much of a deal, as she was something of a loose cannon. Kate is different. She and Prince William are a fairy tale couple.
