LONDON – The eye-popping hat worn by Princess Beatrice at Britain's royal wedding is to be auctioned to raise money for charity, Buckingham Palace said Thursday. The famous creation — which some said looked like antlers_ will be sold on eBay with the proceeds to go to the charities UNICEF and Children in Crisis. The hat was the handiwork of Britain's leading milliner, Philip Treacy, who designed many of the ladies' hats worn at the April 29 nuptials of Prince William and Kate Middleton, now known as the Duke and Duchess of Cambridge.
