LONDON - If dresses could talk, this dark navy, figure-hugging velvet number would have the best stories to tell.

Princess Diana wore it on state visits, at royal banquets, and most memorably to a gala dinner at the White House in 1985 when she took to the dance floor with Hollywood star John Travolta.

The Victor Edelstein gown will go under the hammer at a vintage fashion auction in London in March, along with nine other of Diana's lavish evening dresses. In total, Kerry Taylor Auctions say the sale is expected to raise more than 800,000 pounds (US$1.2 million.)

The dresses, all in the signature 1980s look — padded shoulders, puffed sleeves, crushed velvet — are snapshots in the princess's glamorous, jet-setting life.

One Catherine Walker long-sleeved gown in sea-green sequins was worn to a grand Vienna theatre; a burgundy velvet gown with a plunging back, by the same designer, was paired with the Spencer tiara on a visit to Canberra, Australia; and a black, beaded velvet gown, also by Walker, was worn in 1997 for a Vanity Fair photo shoot by Mario Testino.

But the most celebrated item was the Edelstein gown with off-the-shoulder straps, which Diana chose for her and Prince Charles' first joint visit to the White House.

The princess paired it with a stunning sapphire and pearl choker for a state dinner given by President Ronald Reagan, where, after dinner, she and Travolta twirled on the White House dance floor to tunes from the actor's hit movie "Saturday Night Fever."

Travolta said afterward: "She turned around and she did that look that she did so, so beautifully and I asked if she would care to dance and she said she'd love to."

The gown, which Diana wore on at least four other occasions, is expected to sell for up to 300,000 pounds.

The other dresses, valued from 30,000 pounds to 120,000 pounds, include a pale pink A-line gown and bolero set, both richly embroidered in crystals and sequins; a one-shouldered cream and floral-embroidered number; and a white chiffon cocktail dress with a draped skirt.

Diana decided to sell dozens of her dresses at a New York charity auction at the suggestion of her son, Prince William, in 1997 — three months before she died in a Paris car crash. Florida-based socialite Maureen Dunkel bought about a dozen of the dresses — including the ten to be sold next month — and put them up for auction in Canada in 2011, but the prices were set too high and many dresses didn't sell.

Kerry Taylor Auctions declined to disclose the identity of the sellers for the dresses in the upcoming auction. Taylor said only that this time the prices are "realistic" and buyers have already shown interest.

The sale is set for Mar. 19.

  • "I think when I came into marriage -- especially when you've had divorced parents like myself... You'd want to try even harder to make it work and you don't want to fall back into a pattern that you've seen happen in your own family. I desperately want it to work; I desperately love my husband and I wanted to share everything together. And I thought that we were a very good team."

  • "As for becoming queen, it was never on the forefront of my mind when I married my husband. It was a long way off, that thought."

  • "The higher the media places you, the bigger the drop. I was very aware of that."

  • "It took a long time to understand why people were so interested in me, but I assumed it was because my wonderful husband had done a lot of wonderful work leading up to our marriage and our relationship. But then, over the years, you see yourself as a good product that sits on a shelf and sells well. People make a lot of money out of you."

  • On her marriage to Prince Charles: "Here was a fairy story that everybody wanted to work. So it was isolating, but it was also a situation where you couldn't indulge in feeling sorry for yourself. You had to either sink or swim and you had to learn that very fast."

  • On her marriage to Prince Charles: "I was very daunted. As far as I was concerned, I was a fat, chubby 21-year-old, and I couldn't understand the level of interest."

  • On her marriage to Prince Charles: "No one sat me down with a piece of paper and said, 'This is what's expected of you.'"

  • About becoming pregnant with Prince William: "I felt the whole country was in labor with me."

  • About her postnatal depression: "Well maybe I was the first person ever to be in this family who ever had a depression or was ever openly tearful. Obviously, that was daunting because, if you've never seen it before, how do you support it?"

  • "When no one's listening to you, all you feel when no one's listening to you, all sorts of things start to happen. For instance, you have so much pain inside yourself that you try and hurt yourself on the outside because you want to help. But it's the wrong help you're asking for. People see it as crying wolf or attention-seeking, and they think, because you're in the media all of the time, you've got enough attention. But I was actually crying out because I wanted to get better in order to go forward and to continue my duty and my role as wife, mother, Princess of Wales."

  • "I didn't like myself; I was ashamed that I couldn't cope with the pressures."

  • "I was compelled to perform. When I say perform, I was compelled to go out and do my engagements and not let people down and support them and love them. In a way, by being out in public, they supported me although they weren't aware of just how much healing they were giving me. It carried me through."

  • "I had bulimia for a number of years. That's like a secret disease you inflicted upon yourself because your self esteem is lowered and you don't think you're worthy or valuable. You fill your stomach up four or five times a day, some do it more, and it gives you a feeling of comfort. It's like having a pair of arms around you, but it's temporary. Then, you're disgusted at the bloatedness of your stomach and then you bring it all up again. It's a repetitive pattern that is very destructive to yourself... It was a symptom of what was going on in my marriage. I was crying out for help but giving the wrong signals. People were using my bulimia as a coat on a hanger. They decided that was the problem. Diana was unstable."

  • "My husband and I had to keep everything together because we didn't want to disappoint the public. And yet, there was a lot of anxiety going on within our four walls."

  • "We had the media who were completely fascinated by everything we did. It was difficult to share that load, because I was always the one who was pitched out front, whether it was my clothes, what I said, what my hair was doing, everything. Pretty dull subjects, actually, and it's been exhausted over the years. Actually, what we wanted supported was our work as a team."

  • How the press interest affected her marriage: "It made it very difficult, because for a situation where it was a couple working in the same job -- we got out the same car, shook the same hands, my husband did the speeches, I did the hand-shaking. So basically, we were a married couple doing the same job, which is very difficult for anyone and more so if you've got all of the attention on you. We struggled a bit with it; it was very difficult. And then, my husband decided that we do separate engagements, which was a bit sad for me because I quite liked the company. But, there again, I didn't have the choice."

  • "I was portrayed in the media that, if I remember rightly, as someone, because I hadn't passed any O Levels and taken any A Levels, I was stupid. I made the grave mistake of saying to a child I was thick as a plank in order to ease the child's nervousness, of which it did, but that headline went all around the world. I rather regret saying it."

  • "I don't think I was allowed to have any [interests]. I think that I've always been the 18-year-old girl he got engaged to, so I don't think I've been given any credit for growth. And, my goodness, I've had to grow."

  • "Anything good I ever did, nobody ever said a thing, never said 'well done' or was it OK. But if I tripped up, which invariably I did, because I was new at the game, a ton of bricks came down on me."

  • "Yes I was [aware of Prince Charles' relationship with Camilla], but I wasn't in the place to do anything about it... A woman's instinct is a very good one."

  • "There's no better way to dismantle a personality than to isolate it."

  • "Well, there were three of us in this marriage, so it was a bit crowded."

  • "We were a very good team in public, albeit what was going on in private."

  • On the outcome of <a href=",,658866,00.html" target="_hplink">Andrew Morton's book</a>: "We got the lawyers together, we discussed separation. Obviously, there were a lot of people to discuss it with: the prime minister, Her Majesty."

  • "We had struggled to keep it going, but obviously we ran out of steam. In a way, I suppose it could have been a relief for us both that we had finally made our minds up. But my husband asked for a separation and I supported it."

  • "I come from a divorced background. I didn't want to go into that one again."

  • On telling her children about the separation: "I went down a week before [the announcement was made] and explained to them what was happening. They took it as children do, with lots of questions. And I hoped I was able to reassure them, but who knows?"

  • "I think the announcement had a huge effect on me and Charles, really. The children were very much out of it in the sense that they were tucked away at school."

  • "People's agendas changed overnight. I was now the separated wife of the Prince of Wales. I was a problem. I was a liability. And how are we going to deal with her? This hasn't happened before."

  • "Everything changed after we separated, and life became very difficult then for me."

  • On how the details of an alleged telephone call with James Gilby were released: "I felt very protective about James, because he had been a very good friend to me and was a very good friend to me. And I couldn't bare that his life was going to be messed up because he had the connection with me."

  • On how the details of an alleged telephone call with James Gilby were released: "He is a very affectionate person, but the implications of that conversation were that we had an adulterous relationship, which was not true."

  • On how the details of an alleged telephone call with James Gilby were released: "It was done to harm me in a serious manner. That was the first time that I had experienced what it was like to be outside the net, so to speak, and not be in the family."

  • "I'll fight until the end, because I believe that I have a role to fulfill and I've got two children to bring up."

  • On why she withdrew from public life: "The pressure was intolerable then and my work was being affected. I wanted to give 110% to my work and I could only give 50. I was constantly tired, exhausted because the pressure was just... It was so cruel. So I thought the only way to do it was to stand up and make a speech and extract myself before I started disappointing and not carrying out my work. It was my decision to make that speech, because I owed it to the public to say, 'Thank you. I'm disappearing for a bit, but I'll come back.'"

  • "The campaign [against me] at that point was being so successful, but it did surprise the people who were causing the grief. It did surprise them when I took myself out of the game. They hadn't expected that. And I'm a great believer that you should always confuse the enemy."

  • "The enemy was my husband's department, because I always got more publicity, my work was discussed much more than him. From that point of view, I understand it, but I was doing good things and I want to do good things. I was never going to hurt anyone. I was never going to let anyone down."

  • "I put it to William, specifically, that if you find someone you love in life, you must hang onto it and look after it. If you are lucky enough to find someone who loves you, then one must protect it."

  • "William asked me what had been going on and could I answer his questions, of which I did. He [asked], was that the reason that our marriage had broken up. And I said, 'Well there were three of us in this marriage and the pressure of the media was another factor. So the two together were very difficult. Although I still love papa, I couldn't live under the same roof as him and likewise with him.'"

  • "[William] is a child that's a deep thinker, and we won't know for a few years how it's gone in. But I put it in gently, without resentment or any anger."

  • "I take some responsibility that our marriage went the way it did. I'll take half of it, but I won't take any more than that because it takes two to get into a situation."

I was absolutely devastated when this book appeared, because I had trusted him and because, again, I worried about the reaction of my children. And yes, there was factual evidence in the book, but a lot of it comes from another world. It didn't equate to what happened."

  • On the publishing of <a href=",,20104143,00.html" target="_hplink">the book in which James Hewitt exposed their relationship</a>: "It was very distressing that a friend of mine who I had trusted made money out of me.

  • "Living in Kensington Palace is a little isolating, but maybe we all feel like that."

  • "I actually don't like being the center of attention. When I have my public duties, I understand that when I get out of the car, I'm being photographed. But actually it's now when I got out of my door, my front door, I'm being photographed. I never know where a lense is going to be."

  • "A normal day would be being followed by four cars. A normal day I would come back to my car and find six freelance photographers jumping around me... They've decided that I'm still a project after 15, 16 years that sells well and they all shout at me telling me that. 'Oh come on Di, look up. If you give us a picture, I can get my children to a better school.' You can laugh it off, but when you get that the whole time, it's quite difficult. "

  • "I am a free spirit, unfortunately for some."
