An ivory chiffon dress by designer Zandra Rhodes, worn by Princess Diana to a benefit in 1987, is auctioning at Nate D Sanders.
The dress carries an opening bid of $55,000, with the sale due to close on March 27.
The dress originally sold for $41,400 in a 1997 auction at Christie's New York organised by Diana herself - with the proceeds going to charity.
It then sold at Kerry Taylor Auctions in London in March 2013 where it achieved £48,000 ($80,000), equating to a return of 4.2% pa over 16 years.
