Members of the royal family are supposed to wear neutral colors while carrying out official duties. This guideline was established by Queen Elizabeth II, who discouraged royals from wearing bright, distracting hues on their nails.
However, this wasn’t the first time a royal broke this rule. Back in 2019, Meghan Markle attended Cirque du Soleil with her husband, Prince Harry, and wore dark polish on her toenails.
During the Easter Sunday service, Princess Catherine coordinated with her entire family, who also wore royal blue. Prince William, 40, and Prince George donned matching navy suits, while Princess Charlotte wore a blue-and-white floral dress with baby blue stockings and navy flats. Last but not least, Prince Louis wore a navy blazer with bright blue shorts and high socks.
