The stunning white dress was a floor length number appropriate for a formal dinner.
The gown had cap sleeves and a sweetheart neckline.
The Duchess of Cambridge wore a purple sash and carried a small white clutch bag.
Kate Middleton wore a tiara made famous by Diana and the Queen Mother’s earrings.
It was anticipated that Kate Middleton would attend tonight, while Meghan Markle was expected not to attend.
The Duchess of Sussex has recently given birth to her first child Archie Harrison.
Prince Harry did meet Donald Trump and his daughter Ivanka today although his body language was called “cold”.
This may be a response to the fact Donald called Meghan “nasty” in a recent interview.
Judi James told Express.co.uk of Harry’s behaviour at Westminster Abbey today: “Given the controversy over Meghan’s comments about Trump and his about her Harry does look unsurprisingly but also uncharacteristically wary and solemn in these poses.
“He stands here doing what looks like watching rather than joining in, with a cold or deadpan facial expression and what looks like a reflective eye-gaze.”
How did Kate Middleton become a royal?
Kate Middleton, or Catherine, Duchess of Cambridge, was born on 9 January 1982 at the Royal Berkshire Hospital, Reading, England.
She was born to Michael and Carole Middleton, a former flight dispatcher and air hostess. The couple founded a party supplies company, Party Pieces, in 1987 – now estimated to be worth £30 million.
Kate has a younger sister Pippa Matthews, 34, and a younger brother James Middleton, 31.
Kate and her family moved to Amman, Jordan, in 1984, where the future Duchess was educated at an English-speaking nursery school.
After moving back to Berkshire the family sent Kate to private school, St Andrews School. She went on to briefly study at Downe House before moving onto Marlborough College where she boarded.
For university the young Kate attended the University of St Andrews in Fife, Scotland. Here she was awarded an undergraduate MA (2:1 Hons) in history of art.
Relationship with Prince William
Kate met Prince William when they were both studying at St Andrews, and both living in St Salvator’s Hall. Famously, William reportedly took a fancy to Kate after she wore a see-through dress during a fashion show.
In 2003 the couple began dating and lived together during their second year of university.
The couple split in April 2007, however, in October they were back together.
Prince William proposed to Kate Middleton with his late mother Princess Diana’s engagement ring in October 2010. The couple were holidaying in Kenya at the time.
On 29 April 2011 they married at Westminster Abbey with a whopping 26 million watching the event live.
Kate wore an Alexander McQueen dress worth a reported £250,000 on the big day.
Kate assumed the title “Her Royal Highness The Duchess of Cambridge” and also become the Duchess of Cambridge on the day.
