Prince William and Catherine Middletondepart for North America on June 30th, and we can’t wait to see what she wears! And because we just can't help but wonder what the Duchess of Cambridge stashed inside her suitcases, we decided to do some imaginary packing for her. Based on her effortlessly chic style for casual and formal daytime looks, beautiful evening gowns, and fun fascinators, click through the gallery to see what we chose for the new Royal's North American tour—Zara, Reiss, McQueen, and all.
