On Tuesday, Princess of Wales Kate Middleton made a rare public appearance amid her cancer recovery.
She appeared with her husband Prince William during welcoming the Emir of Qatar Sheikh Tamim bin Hamad Al Thani and his wife Her Highness Sheikha Jawaher bint Hamad bin Suhaim Al Thani.
The Qatari Royal couple is making their first-ever state visit to the UK where it is welcomed at the "ceremonial welcome."
The Prince and Princess of Wales were the earliest members of the UK Royal family to receive the Emir of Qatar.
It is expected that Queen Camilla will be at the lunch reception for the Qatari Royal couple.
The Princess of Wales chose an impressive trendy, and classy outfit that reflected the occasion’s significance. She wore a burgundy coat by Sarah Burton for Alexander McQueen, to represent the colors of the Qatari flag.
In addition, her jewelry included the late Queen Elizabeth's Bahrain pearl drop earrings and Japanese pearl choker, which symbolizes the heritage of the Royal Family, and the UK's historical foreign ties.
