Right before she married Prince Charles, Lady Diana Spencer wore a similar design, which even included a polka-dot print.
This isn't the first time the couple's children have gone viral for clapping for the UK's National Health Service. Kate and William shared footage of George, Charlotte, and Louis applauding for NHS last month too. "To all the doctors, nurses, carers, GPs, pharmacists, volunteers and other NHS staff working tirelessly to help those affected by #COVID19: thank you," their team wrote in the Instagram's caption. "#ClapForOurCarers #ClapForCarers #ThankYouNHS #ClapForNHS"
