A revealing dress worn by Kate Middleton at a 2002 charity event attended by Prince William back in college has sold for 65,000 pounds ($104,860) at auction.

The black see-through dress with a blue trim was bought by an unidentified buyer Thursday in London, reports The Associated Press. It was originally expected to reach 8,000 pounds, already excluding the 20 percent buyers’ premium.

The dress, made by Charlotte Todd, was initially intended to be worn as a skirt, but Middleton wore it as a short dress with black lingerie underneath. It is also said to have played a role in sparking the royal romance that started shortly after the event.
