Kate started with a foundation of black skinny jeans and black wedge booties and then threw on a navy blue sweater, complete with a flouncy white peplum hem. While Kate's top was all one piece, you can easily re-create the same silhouette with a blouse and a fitted top in a similar shade. Grab your go-to accessories, like Kate's oversize sunglasses, her Saint Laurent satchel, and a simple dainty ring, and you're ready to jet-set . . . or just turn heads on the street.
