On Monday afternoon, the Duchess of Cambridge joined her husband Prince William, Prince Charles and the Duchess of Cornwall, as they attended the Commonwealth Day service at Westminster Abbey.

Kate looked incredible in her dazzling outfit. The mother-of-three wore a truly eye-ctaching blue dress that was cut in a unqiue blazer-style design by Catherine Walker London. She wore her hair in a long, loose style with perfectly coiffed curls and her makeup was as flawless as ever. She finsihed off her crowning glory with a vibrant blue hat that looked like a headband from the top. We loved her simple jewellery and smart clutch bag, as well as co-ordinating blue heels.

Prince Charles stepped in to represent the Queen, who had decided not to travel from her home in Windsor. This was the first time Her Majesty had missed the event in almost a decade and it would have marked her debut public appearance since reaching her Platinum Jubilee milestone in February. The last time the Queen skipped the service was in 2013, while recovering from a nasty bout of gastroenteritis.

The decision of the monarch, who has just recovered from coronavirus, not to attend has been interpreted as a precautionary measure and a practical move, rather than a new health issue.

Charles was joined by his wife Camilla, as well as William and Kate, and also Princess Alexandra. The Duke and Duchess of Gloucester were due to attend but had to miss the event due to the Duke's positive coronavirus test.

Today is particularly special as Commonwealth Day has not been celebrated in person since 2020. That year, Prince Harry and Meghan made their last public appearance with other senior members of the royal family before moving to North America.
