The revenge dress
When Princess Diana stepped out in 1994 for the Vanity Fair event wearing the little black Christina Stambolian dress, it was immediately labelled the 'revenge dress.'
That very evening, her then-husband Charles made the adultery confession on television. But it wasn't him that gained everyone's attention, it was Diana, the People's Princess.
Emerald choker
While Diana donned the emerald choker on numerous occasions, but during a gala dinner in Melbourne, Australia in 1985 she wore the necklace as a headband for the first time. She paired the statement jewellery with a teal gown designed by David and Elizabeth Emanuel.
The piece, worth around $20 million, was gifted to Diana by the Queen.
The Cannes Film Festival
At 26-years-old, Diana strutted into the Cannes film festival in an icy powder-blue tulle gown featuring a scarf which she tied behind her to flow like a train.
Diana worked on the piece with Catherine Walker, inspired by Grace Kelly's character in To Catch A Thief.
James Bond Premiere
In July 1985, the Princess arrived at the London premiere of the James Bond film 'A View To A Kill' wearing a gold reflective evening gown designed by Bruce Oldfield.
Black and White
While Diana is mostly pictured wearing colourful gowns and outfits, its rare to see the Princess in a black and white suit. But oh my does she look stunning.
In November 1987, Diana arrived at a reception at the city hall in Munich wearing a checked suit by Alistair Blair.
Jewels, jewels, jewels!
Diana's beautiful jewellery were certainly on display during a state reception in Brisbane, Australia in 1983.
The Princess wore the Spencer Family Tiara with sapphire and diamond jewels which were a gift from the Crown Prince of Saudi Arabia.
