The odd Philip Treacy-designed hat Princess Beatrice wore at last month's royal wedding sold for about $130,000 (GBP 81,000) in an eBay auction this weekend.
The proceeds for the famous headpiece will be forwarded to UNICEF UK and Children in Crisis. An anonymous buyer edged four other bidders for the privilege of calling the royal memento his own.
"It has its own personality, and I am so happy that we have raised the most incredible amount of money and can make an even bigger change for the lives of some of the most vulnerable children across the world," the 22-year-old daughter of Prince Andrew and Duchess Sarah Ferguson said in a statement on Sunday.
As previously reported, Prince William and Kate Middleton wed April 29 at Westminster Abbey, as an estimated worldwide audience of 2 billion people watched.
