Three daywear outfits worn by late Princess Diana at different events in in the 1980s were sold for $334,215 at London's Kerry Taylor Auctions earlier this month.
The pieces fetched nearly three times the price they were originally expected to sell for.
"Diana's day wear is much rarer than her evening wear, which she auctioned a huge tranche off in the late 1990s," the auction house's founder, Kerry Taylor, told the Daily Mail.
"Day wear dresses she wore for more formal functions she either gave to friends or charity shops, so they have mostly disappeared. These were very well documented outfits and one-of-a-kind as they were made specifically for her,” he said.
The sold dresses include a Catherine Walker outfit that the princess wore during the President of the Republic of Turkey's state visit in 1988, an outfit designed by David and Elizabeth Emanuel from a visit to Bahrain with Prince Charles in 1986, and a Jasper Conran red suit that Diana wore as she christened the cruise liner Royal Princess in 1984.
