Natasha Archer, credited with finessing the princess’s signature high-low look, is striking out on her own after 15 years at Kate’s side.

For her state banquet gown, Kate chose a dark red Givenchy evening gown designed by Sarah Burton, who also designed the princess's wedding dress. Kate and William shared their looks ahead of the state banquet on social media, captioning a photo, "Ready for what promises to be a wonderful State Banquet this evening in Windsor."
