In the 80s and 90s, British royals such as Princess Diana and Sarah Ferguson hopped on the growing trend for matching family outfits.
Brothers Prince William and Prince Harry frequently donned identical outfits, while Sarah and Prince Andrew's two daughters Princess Beatrice and Princess Eugenie enjoyed countless twinning moments.
Prince Harry and Prince William were often dressed in matching outfits
The Duke of Sussex has since made light of his mother's twee habit. Speaking in the documentary, Diana, Our Mother: Her Life and Legacy, the father-of-two said: "I genuinely think she got satisfaction out of dressing myself and William up in the most bizarre outfits – normally matching.
"It was weird shorts and little shiny shoes with the old clip-on. Looking back at the photos it just makes me laugh and I think, 'How could you do that to us?'"
And they weren't alone… Princess Anne appeared to follow suit, opting to dress her children Peter Phillips and Zara Tindall in adorable coordinating outfits.
