When Princess Diana danced with John Travolta at a 1985 White House dinner, the world was awestruck.

Now one very lucky Englishwoman gets to have all that glamor to herself. An anonymous bidder purchased the midnight-blue velvet Victor Edelstein evening gown – the one that prompted Travolta to call Diana “the most beautiful woman in the room” – for more than $362,000 Tuesday at London’s Kerry Taylor Auctions.
