The see-through dress that helped Kate Middleton catch Prince William's eye is expected to sell for at least £10,000 at auction on Thursday.

The knitted, sheer dress, designed by Charlotte Todd, was expected to sell for between £8000 to £10,000 but, after sparking interest from buyers around the world, is now expected to reach far more.

Kate wore the dress with black underwear underneath when she took part in a charity fashion show at the University of St Andrews in 2002.

Prince WIlliam was in the audience that day, and many believe it was the first moment he began falling for Kate.

Auctioneer Kerry Taylor told the Telegraph: "I am quite astonished by the amount of interest from all over the world, from Korea to Japan to America.

"Literally there's global interest in the dress and that reflects the interest in Kate Middleton.

"Ultimately whoever has the best reason and the biggest bank balance will get it.

"We've got people flying in from America, banks have telephones booked.

"I don't know what it's going to make but I think it's true to say it will go for a lot more than I have said.

"A lot of them are business people, it's possibly for investment and possibly publicity for whatever company they own."

And Kerry joked: "We've not had Prince William on the phone yet. I'm very disappointed."

The Passion For Fashion auction, which will be held in central London on 17 March, will feature more than 250 lots, including two gowns worn by William's mother, Diana, Princess of Wales.
