Quick-thinking Sharon Stone turned a wardrobe malfunction into an auction item at a charity gala on Wednesday (05OCT05) when she invited bidding for the opportunity to fasten her dress.

The cool actress just giggled when her backless ELSIE KATZ gown became unclasped while she was serving as celebrity auctioneer at the Macy's Passport '05 Gala AIDS benefit in Santa Monica, California.

She joked, "You know how it is - you take your clothes off for a movie, and they just keep coming off."

Stone then offered the men in the audience the chance to fasten her up, and one lucky guest paid $500 (GBP278) to do the job.

At another point in the auction proceedings, Stone persuaded tennis ace Pete Sampras, who was present, to add luncheons and tours of his trophy room to two tennis lesson items, which then sold for $35,000 (GBP19,400) each.
