King Charles is commemorating Father's Day amid a rift with his son Prince Harry. On Sunday, June 15, the King's team posted a tribute on the Instagram account that he shares with Queen Camilla to mark the occasion. The annual holiday is celebrated on the third Sunday in June in both the U.K. and the U.S.

The annual display of British military might serves as a seasonally tweaked birthday celebration for the sitting monarch.

The parade travels from Buckingham Palace down The Mall to Horse Guards Parade. Then, following tradition, Charles, Queen Camilla, 77, and other work members of the royal family stoof on the Buckingham Palace balcony to watch a flypast. As the family headed back inside Buckingham Palace, Prince Louis turned and gave the crowd one final wave.

Princess Diana left behind a legacy of iconic fashion moments in the years following her tragic death in 1997. Among some of the best pieces in her royal wardrobe, Diana styled a number of elegant, sophisticated and modern looks for the annual Trooping the Colour event that takes place in the U.K. every summer.
