Kate Middleton caused major excitement yesterday when she hit High Street stores — clad in a black Issa dress and tan kitten heels — to pick up summery pieces worthy of, ahem, a vacation or perhaps a honeymoon, if one were just married. Regardless of why Kate was in the market for Summer clothes, on the eve of her royal wedding, it's nice to see her out shopping like a normal person. At Warehouse, she picked dresses with tropical prints, and according to the Daily Mail, at Peter Jones she chose a pair of Marc Jacobs sunglasses, and blue and white trousers and a yellow top from Whistles. She even hit up a London outpost of Banana Republic, although the retailer refuses to divulge any details. What are your honeymoon essentials?
