Catherine wore a stunning new hat at the wedding of William’s Cousin Zara Phillips to Mike Tindall in July 2011. The wide brim hat was termed as Potato Chip due to its shape. It was reported at that time the Duchess herself was involved in the designing of the hat. Designer Gina Foster created the stunning straw-coloured hat and Catherine added the floral touch to it. The wide brim cocktail hat featured cabbage rose shaped flower inside the brim.
