The designer is a British favorite for superstar and fashionista shocker Lady Gaga, as well as First Lady Michelle Obama and Sarah Jessica Parker.
The ivory and lace dress is being hailed as the perfect choice for Middleton, with People magazine calling it "modern yet reserved."
Ever the stylish bride, Kate helped design the dress, and even did her own makeup for her big day! Prepping her hair for the wedding was also an event, with two hours of washing, blow-drying and curl-setting the night before, followed by another two hours in the morning.
The blushing bride also plans to change her look for the reception with a new 'do and dress.
