Prince William and Prince Harry are set to receive Princess Diana's wedding gown. According to The Telegraph, Diana's will stipulated that her brother, Earl Spencer, would "look after" the dress until Harry's 30th birthday, which is September 15.
The dress, which Diana wore when she said "I do" to Prince Charles in 1981, was designed by David and Elizabeth Emanuel. The silk-and-taffeta lace dress, which features thousands of pearls, silk layers and a 25ft-train, has been part of an exhibition called "Diana: A Celebration". The dress was displayed around the world, most recently at the Cincinnati Museum Center in the U.S.
