"Kate looked so beautiful, she's got such an amazing sense of grace and style - it was quite easy to make her look good," Burton told The Telegraph. "It was a real labour of love and a real collaboration, for me it was a huge highlight of my career. It came completely out of the blue, it was very exciting and I felt very privileged."
Yesterday, Burton visited Buckingham Palace tocollect her OBE from Prince Charles - a man she believes has "an amazing sense of style" and "impeccable taste". The conversation soon turned to the royal baby.
"We talked a little about the dress and I said congratulations for the Duke and Duchess - I'm over the moon for them," she said.
