It is no secret that Princess Diana is a fashion icon.
Like Kate Middleton and Megan Marchell today, people ignored her clothes and desperately wanted to know what the princess was carrying.
Over the years, Diana's teams have become increasingly adventurous.
You can remember her iconic black garments from 1994, which is being worn the same night when the world discovered that Prince Charles had a relationship with Camilla.
However, there is another dress that Diana wore, which turned her head – a dressed Dior dress.
The dress with a lace upholstery was worn by a mother of two at the annual Met Gala in New York in 1996 and is now considered a key part of fashion history.
This is due to the change in Diana's fashion evolution when she moved away from her conservative royal outfit.
But it turns out that Diana almost did not wear the dress that night – and there's an interesting reason why.
According to MailOnline, Diana was worried about her son's reaction to see her in the dress.
She was worried that Prince William, then at the age of 14, would have been embarrassed how revealing the dress of the then 35-year-old was.
Those who are not familiar with the beautiful silk dress that Diana combines with pearls and sapphires now have a chance to see her personally.
The glamorous dress is currently exhibited at the Victoria and Albert Museum in London as part of their new Christian Dior exhibition.
The exhibition, Christian Dior: Designer of Dreams, has been included in the museum from now until July, with the entrance for adults costing between 20 and 24 pounds.
Diana's fashion choice was not the only cause for concern for young Prince William.
According to Royal Biographer Katie, Nicole William was also "embarrassed" by his mother's public life.
For her biography of 2010, William and Harry, Katie talks with William's childhood friend Kitty Dumble, who revealed everything.
She said, "I remember that William was distracted by what is happening at home.
"At that time there were many things in the papers that the marriage of Charles and Diana was in trouble.
She added, "William told me," Father never bothers me, but sometimes Mom. "
