The Princess of Wales left people dazzled as she wore an ivory silk crepe gown Alexander McQueen dress, which featured silver bullion and thread work embroidery featuring rose, thistle, daffodil and shamrock motifs to represent each of the four nations for the Coronation.
In a touching tribute to her husband's late mother, the polished princess added a pair of pearl and diamond earrings belonging to Diana, Princess of Wales.
But it appears she may have made a last minute change to the outfit, as one of the glitziest items she was due to wear couldn't be seen on the same.
She was expected to wear Queen Elizabeth II’s George VI Festoon Necklace, which George VI commissioned for his daughter Princess Elizabeth in 1950.
The statement necklace features a three-strand diamond design containing 105 loose collet-set diamonds from the royal vault into a necklace, introduced into the crown collection by his mother, Queen Mary.
We don't know exactly what happened, but it may have been removed in order not to overwhelm her Royal Victorian Order mantle edged in scarlet that was topped with a silver bullion, crystal and silver thread work three-dimensional leaf embroidery headpiece by Jess Collett x Alexander McQueen.
Charlotte, who exchanged affectionate smiles with her mother during the service, was a mini-me version of Kate, with a similar headpiece by the same milliner and an ivory silk crepe Alexander McQueen dress which featured the same rose, thistle, daffodil and shamrock motifs as her mother’s.
Despite the formality of the occasion, Kate looked relaxed and gave a beaming smile as she listened to the performance of Alleluia by the Ascension choir – a gospel choir handpicked for the occasion.
Kate smiled down at Louis, seated to her right, when the five-year-old struggled to stay still during the formal ceremony, often glancing at his mother.
The princess was seen bending down to talk to Louis when the congregation stood for a hymn, shortly before the five-year-old left the front row of the abbey for a short time.
George joined his family for the carriage ride back to Buckingham Palace and all five were seen smiling and waving to well-wishers.
The prince then stood happily with the King’s other pages of honour for the royal family’s appearance on the palace balcony while Louis and his sister Charlotte joined their parents.
Kate, with some help from the Duchess of Edinburgh, encouraged Louis and Charlotte to move along so they were closer to her.
She kept a close eye on the young prince, placing a reassuring hand on Louis’ shoulder and encouraging him to look up when the aircraft approached for the flypast.
