In the portraits, Kate Middleton wore a blue patterned dress that was reportedly recycled from previous private engagements. She wore a diamond necklace that she has not been seen in before.
It had a mixed floral print on the bodice with a blue polka dot design on the skirt.
The Duchess of Cambridge completed the look with a subtle diamond necklace.
The ‘Daisy Heritage Pendant, Diamond’ was designed by Asprey London and costs £8,840.
It features a daisy flower made out of diamond hanging from a silver chain.

The description read: “This Daisy Heritage piece is one of the most iconic of such designs, featuring individually set marquise cut stones as the flower’s petals.
“Each is held in place with two perfectly formed V-shaped claws, designed to allow maximum light to pass through the stone.
“The centre of the flower, meanwhile, is set with a half ball of pavé diamonds, replicating the texture of the daisy’s centre.”
The Duchess of Cambridge is no stranger to wearing stunning pieces of jewellery.
Following the birth of their first child, Prince George, the Duchess reportedly received a diamond eternity ring from Prince William.
She often wears the jewel on her wedding ring and it has been given a valuation of up to £2,000.
In 2011, she showcased a pair of green amethyst and diamond earrings at the royal Christmas Day church service.
The drop earrings were from designer Kiki McDonough and believed to be a present from Prince William to celebrate their first festive period as a married couple.
The royal line of succession – who outranks who?
The line of succession to the British throne dictates the order in which each member of the Royal Family would ascend to the throne.
It is also seen as a ranking of importance with the head of the line, the Queen, taking the place of ruler.
Older children come before younger children. Traditionally boys came before girls, but this law was changed on 26 March 2015 before the birth of Prince William’s first child.
Incredibly, Catholics are still excluded from the line of succession, as are children born outside of wedlock.
The royals, who usually stick to a strict protocol when appearing in public, often arrive at events in ascending order of importance, with the most important royal arriving last.
Prince Charles, 72, is currently first-in-line to the British throne, followed by Prince William, 38, his oldest son.
Then comes Prince William’s children, George, seven, Charlotte, five, and Louis, two, and they are followed by Prince Harry, 36. Prince Harry is succeeded by his son Archie Harrison, born in May 2019.
