TORONTO - Several of the most famous gowns worn by Princess Diana are set to hit the auction block this summer in Toronto.

Waddington's auction house says 14 dresses will be up for grabs, including garments by British designers Victor Edelstein, Bruce Oldfield, Zandra Rhodes and Catherine Walker, who was a favourite of the late princess.

Highlights include the dress Diana wore at the White House state dinner hosted by then-president Reagan and his wife, Nancy, when the princess famously danced with actor John Travolta.

The sale will also include three dresses Diana modelled during her 1997 photo shoot for Vanity Fair magazine, and another she sported for an official portrait.

The garments are part of a collection owned by Maureen Rorech Dunkel, of Tampa Bay, Fla., who bought the dresses anonymously at Christie's New York on June 25, 1997, eight weeks before the princess died.

The dresses hit the auction block June 23 in Toronto.
