It's hard to believe, but July 1, 2021, marks what would have been Princess Diana's 60th birthday. To honor the late royal, who died following a devastating 1997 car accident in Paris, Kensington Palace unveiled a statue of the Princess of Wales on her birthday — an event that reunited her sons, Prince William and Prince Harry. In anticipation of the event, Wonderwall.com is taking a look back at some of the most memorable moments from her too-short time in the spotlight. Let's start with the evening she wore this dazzling Christina Stambolian LBD to a charity dinner at the Serpentine Gallery in 1994. It was soon nicknamed the "revenge dress" because Di donned it on the same evening a TV interview with Prince Charles aired in which he confessed to adultery.
