The Prince and Princess of Wales attended the Diplomatic Reception this evening at Buckingham Palace.
Hosted by King Charles III for the first time as monarch, the annual white-tie soirée is one of the most formal events on the royal calendar.
Over 1,000 people from around 130 countries, including members of the British government and past Prime Ministers attend the gathering.
The Princess looked regal in a red Jenny Packham 'Elodie' Gown.
The $5,040 long sleeve dress is from the British designer's Pre-Fall 2019 collection.
It features a tonal floral bead & sequin motif throughout.
Kate donned the Lotus Flower Tiara which she complemented with the late Queen's diamond orbital earrings.
The Princess wore the Royal Victorian Order sash and badge, along with the Maltese Cross.
You may recall the Duchess of Cambridge was appointed Dame Grand Cross of the Royal Victorian Order in April 2019 by The Queen for services to the Sovereign.
Kate pinned her recently acquired Bentley & Skinner Art Deco Diamond Set Brooch to the sash.
Affixed to the left side of her dress was the Royal Family Order of Queen Elizabeth II which the Duchess was awarded in 2017.
