Photo of Princess Diana walking into a Genesis concert in a tuxedo designed by Margaret Howell by David Levenson, 1984.
"Princess Diana turns on another stunning performance as she arrives for a concert of one of Britain's top rock bands. There were wolf whistles as Diana walked in wearing a white dinner jacket, satin black trousers, a white full-necked blouse...and a black satin bow tie." —James Whitaker
Thanks to Kate Levine for the idea!
