Catherine, Princess of Wales and Prince William, Prince of Wales arrive ahead of the Coronation of King Charles III and Queen Camilla

There was much speculation about whatKate Middletonwould wear to thecoronationofKing CharlesandQueen Camilla— and her wardrobe delivered.

At the request of the King and Queen,Prince Williamand Princess Kate both wore formal robes and mantels for the historic occasion.

Princess Charlotte, 8, matched her mom in an Alexander McQueen dress with similar designs.

Queen Camilla’s attire was similar — and that was done deliberately, royal embroidererChloe Savage exclusively tells PEOPLE.

“Kate and Camilla together were involved,” says the expert embroiderer, who was previously tapped for both Princess Kate andMeghan Markle’sroyal wedding gowns.

“The whole floral theme, if you look at the train of Camilla, herRobes of Statewhich were custom done, full of floral embroidery. If you noted, all the girls wore floral themes. Floral runs through consistently as a royal family theme down toMeghan’s veil. It’s all significant, what gets used,” she says of the symbolism on display atWestminster Abbeyon Saturday.

Savage had a hand in Kate and Camilla’s formal coronation robes, saying “months” were spent on the ceremonial vestments, and contributed to the Princess of Wales’floral silver headpiece. The Jess Collett x Alexander McQueen topper featured silver bullion, crystal and silver thread work with three-dimensional leaf embroidery — anda mini versionwas made forPrincess Charlotte!

“Everyone had a bit of a go because they needed so many flowers and leaves,” Savage says of her embellishments.

When deciding on what Kate would wear on her head, hats were ruled out, Savage tells PEOPLE: “Of course hats aren’t going to work when you’re going to be photographed from above. It’s going to get in the way of everything, so hats were a no-go.”

And with a tiara out, “custom headpieces was a sensible route. And of course, Kate matched her and Charlotte’s.”

Another fun matching moment? Savage, a graduate of Paris' prestigious École Lesage embroidery school, also notes that “Charlotte’s dress is also a miniature of the one the [Queen’s Companions] wore, in the same cream satin.”
