A sailor-style sweater dress with a drop waist and pleated hemline, Kate chose this first for her visit to Prince Edward Island. The dress was thought to be a nod to the sailing community and possibly to the famous heroine of the island, Anne of Green Gables. Kate has said that the L.M. Montgomery series was a favorite as a child. Sarah Jessica Parker has worn tho dress in navy with white trim. Retail: £1,100
