- Kate Middleton and members of the royal family attended a state banquet on Tuesday.
- Kate wore a Jenny Packham cape dress and a tiara worn by the Queen and Princess Diana.
Kate Middleton attended her first state banquet as Princess of Wales in an outfit that honored the late Queen Elizabeth and Princess Diana.
Kate, who inherited Diana's former title upon King Charles' accession in September, dined with the royal family and South African President Cyril Ramaphosa at Buckingham Palace in honor of his state visit to the UK on Tuesday.
The royal paired a dazzling cape dress by Jenny Packham with the Lover's Knot tiara, as well as a bracelet belonging to the late Queen Elizabeth II and earrings that belonged to Diana, according to the Daily Mail's royal editor Rebecca English.
Kate also wore the Royal Family Order — a badge worn by the royals at formal events — and the GCVO Star and Sash, English added.
The tiara was designed for Queen Mary in 1914 by the House of Garrard using pearls and diamonds already owned by her family, Town & Country reports. In 1953, the tiara was inherited by Queen Elizabeth, who wore it on a number of formal occasions throughout the 1950s.
It's thought that the Queen loaned the tiara to Diana after she married Charles in 1981, Town & Country added. She was photographed wearing it on many occasions, including on a visit to Hong Kong in 1989.
The state banquet on Tuesday marked the first event of its kind since the death of Queen Elizabeth on September 8. Kate wasn't the only royal to pay tribute to the late monarch with her outfit.
Camilla, Queen Consort, paired a blue ball gown with the Belgian Sapphire Tiara, which also belonged to Queen Elizabeth, People reports. Her Majesty was most recently photographed wearing it during a state banquet in honor of former US President Donald Trump in 2019, the publication added.
Kensington Palace and Jenny Packham did not immediately respond to Insider's request for comment.
