@cbsnews: Princess Diana’s iconic “revenge dress” is going up for auction at Sotheby’s in New York City this December. She wore the daring black dress on June 29, 1994, the same night then-Prince Charles publicly acknowledged his infidelity. The dress previously sold for about $54,000 in 1997 and is now expected to fetch up to $300,000, though some people expect it could sell for much more. #unitedkingdom #uktiktok #britain #princessdiana
