A British man who wanted “a surprise to cheer up his wife” walked away Tuesday with the top-selling item from a London auction of Princess Diana’s gowns: a dark navy velvet dress that the princess wore when she danced with John Travolta at the White House in 1985.

The iconic Victor Edelstein gown sold for 240,000 British pounds, or about $362,000 — nearly double what it went for when it was last auctioned in 1997.
