Her life is never out of the spotlight, Princess Diana is also known as a fashionista.

Even Princess Diana's fashion style has become a role model for many women in various parts of the world.

As a British royal family, Princess Diana also always uses branded items designed by well-known designers.

Uniquely, the mother of Prince Harry and Prince William never again wanted to use fashion products from the luxury brand Chanel.

This was done after he officially divorced Prince Charles.

It turns out that the reason behind it is quite heart-wrenching.

In a new interview with Harper's BAZAAR Australia, Australian designer Jayson Brundson discusses his time working with Diana in 1996, during Princess Diana's last visit to Australia for a charity event.

"I am good friends with Joh Bailey and Joh was appointed as his hairstylist when he was here on the visit. He was recently divorced and Joh knew I was a huge fan," said Brundson.

"So when he said to me, 'Will you come as my assistant?' on Saturday and I said, 'Yes of course I will, I like it,' he continued.

One incident when choosing Diana's clothes is still remembered by Brundson today.

Brundson recounts, "I found a pair of Chanel shoes, and I said, 'Well this would look great with Versace,' and he said 'No, I can't wear a C connected, double C.' So I asked why, and he said, 'This is Camilla and Charles.' "

Princess Diana's divorce from Prince Charles ended in August 1996.

But throughout their marriage, Camilla Parker Bowles was reportedly always present between the two of them.

In fact, before Princess Diana's split from Prince Charles was announced, a recording of a romantic phone call between Camilla and Charles was leaked, leading to rumors of an affair.

In a TV interview in 1994, Prince Charles admitted that he committed adultery while still married, but he claims it happened after it became clear that his marriage to Diana could not continue.
