The Princess of Wales wowed royal fans when she arrived at Westminster Abbey for King Charles' Coronation in a show-stopping ivory dress complete with a robe and stunning headpiece.
Within her outfit, Kate paid a subtle tribute to her late mother-in-law, Princess Diana, as she donned a pair of pearl and diamond earrings that had once belonged to Diana and had been gifted to her by her the then-Prince Charles just before their wedding in 1981.
And it wasn't just Diana who received a sweet nod within Kate's outfit either, as she also honoured her late grandmother-in-law, Queen Elizabeth II, as she wore the George IV Festoon Necklace. The necklace was made in 1950 at the request of King George VI for his daughter, the now-late Queen.
The rest of Kate's outfit included a formal robe alongside an Alexander McQueen dress in ivory silk crepe with silver bullion and threadwork embroidery featuring rose, thistle, daffodil and shamrock motifs.
She topped off the breathtaking gown with a Jess Collett x Alexander McQueen Headpiece with silver bullion, crystal and silver threadwork three-dimensional leaf embroidery.
The headpiece Kate wore even twinned with her daughter, Princess Charlotte, who donned a smaller version of the headpiece as well as a matching Alexander McQueen dress.
After arriving, Kate took her seat in the Abbey with her husband Prince William, as well as children Charlotte and Prince Louis, as oldest son Prince George performed his page of honour duties for his grandfather the King.
Kate had no formal role in the Coronation ceremony, although was no doubt looking on with pride as her husband, the Prince of Wales, and eldest son George took part.
William paid homage to his father the King by pledging allegiance to him while George was one of four young boys who were picked to be pages of honour for the monarch.
After the ceremony, Kate along with William, George, Charlotte and Louis will join the procession back to Buckingham Palace behind the gold state coach, where the route has been lined with wellwishers.
In addition, the family will appear on the Palace balcony later where they will greet the huge crowds and enjoy the RAF flypast.
