You bring a breath of fresh air and modern glamour to Monaco.’ " For her civil ceremony, Charlene collaborated with the designer, wearing a pantsuit in a vibrant shade of robin’s egg blue, which has since been dubbed “Charlene Blue.““We wanted something to match the color of my eyes,” she toldVogue. “It’s feminine and keeps with tradition, yet has a little twist that reflects my personal style. I thought it was a nice change to go for trousers instead of a skirt, especially since I’m an athlete and have always kept my clothes clean and simple.”
