Whatever Kate Middleton wears, people want.

And judging by yesterday's auction of the see-through dress that is said to have sparked Prince William's interest in his future bride, they're willing to pay big bucks for it.

The sheer slip dress, which Middleton wore on the runway as part of a student charity fashion show at St. Andrews University in 2002, has sold at a London auction for £65,000, plus a £13,000 buyer's fee (which translates to about $125,884).

The dress (which was actually originally designed to be worn as a skirt), was made by Charlotte Todd for a design school project. The lucky bidder was a private buyer bidding over the telephone via an agent standing at the back of the room, reports CNN. He was only identified as "Nick from Jersey" (the English Channel island).

"It's an iconic piece and he is very happy with the purchase," said the agent. "It's a great addition to his collection."

According to CNN, the dress fetched 10 times what it was expected to. The day before the auction, Kerry Taylor of Kerry Taylor Auctions, said: "I initially estimated (the dress) to fetch £8,000-£10,000 because how do you put a price on this little piece of lace? But I suspect my estimate's going to be smashed through in seconds tomorrow."

Even though other items in the auction included couture dresses worn by Princess Diana and Wallis Simpson's lingerie and handbags, the skimpy black-and-gold silk dress (which cost under $50 to make) was the talk of the auction.

Taylor speculates the popularity of the dress is to do with what it represents. "If we're to believe the reports, it's the dress that caught the prince's eye and captured his heart -- and that's why people want it," she said.
