Pippa Middleton's Black-and-White Outfit: Where to Buy It

After ushering in the fall season with her astounding collection of jeans, Pippa Middleton stuck by her standby denims when she stepped out for a London shopping excursion this weekend. Opting for a black-and-white look—the color-combo now dominating the runways—the royal-in-law donned a pair of Goldsign Misfit slim leg jeans (get them for $218 at saksfifthavenue.com), which she topped with a striped Alice + Olivia Shellen Mock Collar sweater (nab one for $275 at shopbop.com) and Kate Spade New York's Post Street Little Nadine bag (find it for $428 at katespade.com). Alice + Olivia creative director Stacey Bendet Instagrammed a photo of Pippa in the sweater, adding, "How cute is Pippa Middleton in our sweater!" Obviously, we agree—who doesn't love stripes?
