The British royal wore the shimmering, figure-hugging outfit, designed for her by Versace, during a photoshoot with renowned photographer Patrick Demarchelier in 1991.

One of the pictures gained prominence when it was later used for Harper's Bazaar's tribute issue to the princess in November, 1997, three months after her death in August (97).

The piece will be sold by Julien's Auctions in the U.S. on 26 June (15).
