It was the dress that made Prince William notice Kate Middleton. A lot of other dudes at the 2002 Dont Walk charity fashion show at St. Andrews probably noticed her, too. The dress, designed by University of the West of England fashion grad Charlotte Todd (she now works in an aquarium), was supposed to be a skirt. Kate wore the sheer knit number as a dress with nothing but a bra and panties underneath, and the rest is history. And now that dress has fetched $125,871 at auction, the AP is reporting.

The buyer, who shelled out over $125,000 for the dress (it was expected to sell for around $15,000 and cost Todd £30 to make), is an anonymous man, known only as ‘Nick from Jersey,’ the Daily Mail is reporting. His bidder said on behalf of his buyer, “He thinks it’s an iconic piece and is very happy with the purchase.”

And a little more on the dress, in case you were wondering what size Kate was when she wore it: according to CNN, “the dress is made of knitted black-and-gold silk with turquoise blue bands at the top and bottom..the label says the dress has a 28-inch waist, a U.S. size eight.”

While Kate’s fashion choices since dating Wills have erred on the conservative side, the flimsy number she wore in her own style proves she’s got a little style gumption in her. We just hope to see some of that fashion risk-taking on April 29th, when she walks down the aisle (fingers crossed in McQueen).
