Kate Middleton is continuing to return to royal duties.

The Princess of Wales attended her first State Visit today since undergoing cancer treatment, playing a key role in welcoming the Emir of Qatar and his wife, Sheikha Jawaher. She and Prince William then joined the couple at the ceremonial welcome at Horse Guards Parade.

For the occasion, Kate wore an all-burgundy outfit, perhaps a tribute to the Qatari flag. Her coat is by Sarah Burton for Alexander McQueen, and her hat by Sahar Millinery. Meanwhile, she carried a Chanel burgundy calfskin flap bag, one that’s been in her closet for nearly a decade.

The Princess of Wales opted for jewelry with significance and history for her appearance today. She chose the four-strand pearl choker necklace previously worn by Princess Diana. The choker, which features four strings of pearls and a diamond clasp in the center, was crafted by Garrard and gifted to Queen Elizabeth from Japan in the 1970s, but became associated with Diana when she wore it on one of her first royal engagements.

Kate has worn the necklace a few times previously, including to Queen Elizabeth and Prince Phillip’s funerals, and to the celebration of Queen and Prince Philip’s 70th wedding anniversary in 2017. Kate’s earrings, too, belonged to the late Queen: They are the Bahrain Pearl Drop Earrings, which Kate recently wore to Remembrance Sunday.

Tonight, the Princess of Wales will not be in attendance at the State Banquet, as she continues to focus on her recovery.
