Elegant, super chic and always glamorous - Princess Diana was truly a global style icon.

Ten of Diana's iconic dresses are set to go under the hammer in a London auction on the 19th March, and here to show us 6 of the legendary gowns - organiser of the auction Kerry Taylor.

Catherine Walker sea green sequinned gown

  • £30000 - £40000
  • Worn for the state visit to Austria in 1989 with Prince Charles, but Diana was photographed wearing this figure hugging sequinned satin gown many times.
  • This gown is by French designer Catherine Walker, Diana's favourite designer. Catherine was known for creating Princess Diana's dignified show-stoppers and Diana wore over 500 of her designs.
  • Diana wore this piece during the state visit with a diamond and emerald chocker necklace which she had been given as a wedding present by the Queen.

Victor Edelstein midnight blue velvet evening gown

  • £200000 - £300000
  • Diana wore this gown to the State dinner at the White House given by President Regan in November 1985, during which she famously danced with John Travolta, showed her fun-loving side.
  • This is one of the most iconic and famous of all of Diana's dresses. Designer Victor Edelstein made dresses for Princess Diana over an 11 year period and she would often pop into his shop and look through the collections whilst her security guard waited outside.
  • Diana saw this model in his studio in burgundy and requested it be made for her in midnight blue.
  • The fittings for the gown took place in her private apartments at Kensington Palace. At the last fitting, Diana was so delighted with the result that she rushed to show Prince Charles. Victor Edelstein remembers Charles telling Diana that she looked wonderful.
  • In 1985 the royal couple made their first joint state visit to the U.S. It lasted four days and wherever they went they were greeted by thousands of cheering people.
  • * The most memorable image from the trip was of Diana and John Travolta gliding across the White House dance floor to 'You Should Be Dancing' from Saturday Night Fever.
  • In an interview on a chat show, Travolta said that Nancy Regan quietly whispered to him that Diana had only one wish on the American trip - and that was to dance with him.
  • They danced for about 20 minutes to a medley of Grease and Saturday Night fever and Travolta described the experience as being 'like a fairytale' and that Diana had great rhythm.
  • In 1997 Diana chose to wear this dress for her last portrait by Lord Snowdon - and with the same necklace she had worn twelve years earlier.

Catherine Walker burgundy crushed velvet backless evening gown

  • £40000 - £50000
  • Worn for a state visit to Australia and to the film premiere of Back to the Future in 1985.
  • When Diana wore this dress in November 1985 for her state visit to Australia she accessorized it with the famous Spencer tiara.
  • The dress has a low V back and is accented with a silk taffeta bow. When Diana wore it to the Back to the Future film premiere she accessorized it with a long rope of pearls down her back which were knotted at the bottom. However she later complained that, although the necklace looked very chic, that the knot dug into her back during the film.

Catherine Walker pink sequinned ivory crepe gown

  • £40000 - £60000
  • Diana wore this at a banquet whilst on a State visit to Brazil in April 1991.
  • This dress proved to be a favourite with Diana - she also wore it to the film premiere of 'Stepping Out' in 1991 and was photographed laughing and chatting to actress and star of the film Liza Minelli at the party afterwards.
  • Photos of the pair appeared in the press the next day, and according to Andrew Morton's book 'Diana: Her True Story', the morning after the party it was pointed out to Diana that it was not done to attend these occasions.
  • According to the author Andrew Morton Diana and Liza had a touching and honest conversation at the party and they became good friends.

Catherine Walker embroidered pink silk evening gown and bolero

  • £80000 - £120000
  • Diana wore this gown for the state visit to India in February 1992. She was also photographed by Lord Snowdon in the gown in 1997.
  • It was during the state visit to India in 1992 that Diana was famously photographed sitting alone at the Taj Mahal - the monument to lost love, which causes a good deal of comment and speculation in the press at the time. Her official separation from Prince Charles was to be announced in December of the same year.
  • The inspiration for this particular embroidered design came from the lid of an Indian inlaid marquetry box discovered by the designers in a London market.

Catherine Walker Burgundy velvet sheath with embroidered tailcoat

  • £40000 - £60000
  • Diana wore this sumptuous gown for the state visit to Korea in 1992 and to the premiere of 'Steel Magnolias' in aid of the Prince's Trust in February 1990.
  • The design was inspired by the colouring of an imperial Russian court dress and was originally offered to the Princess as a burgundy tailcoat over a ivory silk crepe bustier dress. The Princess, however felt that all burgundy would be more fluid and easier to wear.

Zandra Rhodes white chiffon cocktaild dress

  • £30000 - £40000
  • Worn to the Birthright benefit at the London Palladium in May 1987.
  • This intricate gown has a high V-neck and long, sheer sleeves. It is also decorated with pink glass beads, simulated pearls, and silver and pearlized sequins. Accented with a white satin belt.
  • The dress is by British designer Zandra Rhodes, one of Diana's favourite designers who is renowned for her romantic and lavishly embellished evening clothes. Zandra's multi-cultural interests and bold distinctive designs made her a favourite of Diana.
