Sam McKnight had "no idea" that when he cut Princess Diana's hair short in the early 90s that her change in style would have such an "impact".
The 64-year-old hairstylist chopped off the Princess of Wales' locks after shooting her for a 1991 British Vogue cover - where he used hair clips to make her hair appear shorter - and confessed that he "didn't realise" her change in hairstyle would become so "iconic".
Writing for Vogue Australia, he said: "For that now iconic shoot, I styled her hair so it appeared short for the picture. Afterwards she asked: 'What would you do if I gave you free reign?' and I replied: "I'd just cut it all off."
"Her hair was fabulous, but it was time for a change, and I think she felt that, too. So she said: 'Okay, do you want to do it now?' So I did.
"I had been shooting for Vogue for 13 years by then, so I wasn't nervous to cut her hair. I rarely read the British papers, because I wasn't in London very often, so I didn't realise the impact that haircut would have.
