Sparking timeless trends and endless inspiration, decades later, fans are still trying to recreate her most-coveted looks – from her gym-ready cycling shorts to the headline-hitting 'revenge dress,' and of course, the black sheep jumper that she wore to Prince Charles' polo match in 1983.

Hailing from British knitwear brand Warm & Wonderful, the infamous sheep jumper was created by Sally Muir and Joanna Osbourne, who originally sold their sweaters from a stall in London's Covent Garden Market before opening several shops in the 80s and 90s.

Do you remember the moment you found out that Diana had worn one of your designs?

Shock, surprise and delight when I went to buy the Sunday papers, there was Diana on the front page wearing our jumper!

Why do you think Princess Diana is still a major fashion icon today?

Princess Diana's remarkable sense of style made her the most photographed person in the world, everyone was fascinated. For royals, her choice of clothes was radical: backless dresses, androgynous suits, short evening wear but perhaps most importantly her casual clothes. Cycling shorts, blazers, sweatshirts are still very much in fashion.
