The 22-year-old granddaughter of Queen Elizabeth II put the Philip Treacy creation on sale to raise money for UNICEF and Children in Crisis.
Auction site eBay says a bidder has paid 81,100 pounds ($131,648) for the silk bow hat worn by Princess Beatrice to last month’s royal wedding
The silk hat caused a stir at the wedding of Prince William and Kate Middleton on April 29.
Since then, it has been compared to antlers and a pretzel, and has been photoshopped into scores of unlikely scenarios on the Internet. Forty bidders vied for the prize, but eBay did not reveal the identity of the winner.
The auction ended yesterday.
