A pair of white silk mules were recently sold for $57,000 at an auction in Toulon, France. Why so pricey? Marie Antoinette supposedly wore them during her reign. Newser reports that the shoes feature tricolor ribbons, and that Antoinette may have worn them during the Fête de la Fédération on July 14, 1790 -- a day commemorating the storming of the Bastille a year prior.
