Kate Middleton was in a bright fuchsia dress this morning to stop by the hat-makers Lock & Co. in London. She ran errands in the company of her royal protection officers, even carrying her bags back to her car on her own. Kate and her husband of six weeks, Prince William, are gearing up for their first official social engagement as a married couple this evening. They will attend the annual Ark dinner, where Prince William will announce a new philanthropic endeavor from his Prince's Foundation. The event will also include his premiere speech as a married man. Kate and William have been making the rounds with his family since their big day, including Saturday's Epsom Derby with the queen and Prince Harry.
