A rare and stunning photograph of the late Princess Diana aboard a luxurious yacht has emerged.
Wearing a two piece printed bikini and a baggy button-down purple shirt, the never-before-seen photo shows a super slim and super stylish Diana in her element.
Taken back in 1990, the photograph was shared by Diana’s long-time friend, honorary president of the Valentino Fashion House, Giancarlo Giammetti via Instagram.
In the candid snapshot, the Princess of Wales appears happy and relaxed on board one of Valentino’s private yachts.
“Summer is here TBT princess Diana on the TMblue 1990 #princessdiana #rosariosaxecoburg,” Giancarlo captioned the throwback Instagram post.
Also in the snapshot, which was taken on Valentino’s T.M.Blue One yacht, is Rosario Saxe-Coburg, who is married to Prince Kyril of Bulgaria.

Diana is said to have loved taking to the high seas because it was one of the few places in the world where she could escape her very public life.
The People’s Princess, as she was known, died in a car crash on August 31, 1997 in Paris.
