The infamous dress was sold for a staggering $125,884 (£78,000) to an unidentified buyer at the Kerry Taylor Auctions Passion for Fashion sale in London, England on Thursday (March 17). The lingerie-style dress cost less than $50 and was made as a design school project called ‘The Art of Seduction’.

“I’m thrilled,” says Todd. “Everyone says that the fashion show was when the romance started and when she bagged her prince, so a small part of me will always be part of royal history. It’s madness!”

The 31 year-old Charlotte Todd didn’t know who Kate was when she modeled her creation, but she is honored to be a part of royal history. Prince William and Kate are now engaged to be married in the most-anticipated royal wedding in history (April 29).
