Pale pink roses and white flowers with green leaves filled St. Mark’s Church in Englefield, where the couple said their “I dos” on Saturday. The arrangements, by Lavender Green Flowers, perfectly matched Middleton’s small bridal bouquet and lined the windows and pews and were left up for the public to check out on Sunday.
The flowers continued to cover the venue outside, and the couple kissed under a floral arch as they exited the church.
The floral arrangements “reflected the British countryside in early summer and were filled with fragranced flowers including Sweet Peas, Peonies, garden Roses, Philadelphus, Freesia, Astilbe, and Jasmine,” Sue Barnes, Founder of Lavender Green Flowers, said in a statement to PEOPLE.
“All designs were made to measure and were totally bespoke, taking hours to create and perfect — it really was a labor of love!”
The flowers matched the romantic feel of the ceremony, topped off by Middleton’s custom dress by British designer Giles Deacon featured a cap sleeve, high neckline and featured a corseted bodice with draping to the front and a heart-shaped detail at the back.
The bespoke silk cotton lace was hand appliquéd to create an illusion of the dress having no seams.

Guests leaving the church after the wedding told reporters that the ceremony was lovely.
“It was amazing,” one guest told PEOPLE. “They were so cute. I cried. My makeup was running.” They added that George and Charlotte were “very” well-behaved.
