Kate Middleton's 2002 see-through dress to go under the hammer

Kate Middleton's see-through dress that she wore as part of a university fashion show in 2002 is set to go under the hammer next month.

Her catwalk debut reportedly marked the first time her husband-to-be Prince William first saw the attractive brunette, reports Contactmusic.

Middleton wore the Charlotte Todd knitted slip at a St. Andrews University charity fashion show.

Todd, who now works in an aquarium, has kept the outfit ever since it was returned to her.

The dress will be sold at a Kerry Taylor Auctions sale in March (2011).

"It's definitely a showstopping dress. I'd like to think I played my part in history and in fashion history," Todd said.
