Meghan Markle just broke the internet (again) with a dreamy Instagram photo that had fashion lovers scrambling to identify every single piece she was wearing. The Duchess of Sussex looked like she'd floated straight out of a Nancy Meyers movie in a billowy white dress paired with Stuart Weitzman sandals. Effortless. Elegant. And, predictably, expensive. Her casual-chic sandals are proof that a great flat sandal can anchor an outfit just as well as any heel. But her designer sandals can easily run you a few hundred dollars.
