Sarah Burton found making Princess Catherine's wedding dress a "lovely" experience.
The British designer - who is the creative head of Alexander McQueen - had a great time making the one-of-a-kind gown for her wedding to Prince William, which she believes shows a lot of the 29-year-old beauty's personality.
She said: "It couldn't have been more lovely. It was a collaboration. It was made for her and has a lot of her personality in it."
Sarah added the family - including sister Pippa Middleton, who she also dressed - were "really nice and down to earth".
However, her most memorable time was when she had to hide herself prior to going into the Goring Hotel in London the night before the wedding on April 29, and she confesses the group shared a lot of laughs about it.
Sarah said: "The most fun I had was trying to hide. We laughed a lot about that."
Meanwhile, it has been suggested Catherine - who is now titled the Duchess of Cambridge - was wearing a little known perfume by British brand Illuminum on her big day.
The scent, entitled White Gardenia Petals, is said to have the smell of a "vase of white flowers quivering in the breeze by an open window".
On the company's official website, it adds: "The top note of coconut evokes a seaside location, while heart notes of muguet, ylang ylang and jasmine breeze bring a trio of white flowers into play.
"Amber wood underscores this capricious and light bouquet."
