Rejina Pyo's Lottie sandals evoke a distinctly '90s vibe thanks to a severe squared toe. This effortless silhouette has been crafted in Portugal from buttery suede in a sage green hue and comes set on the label's signature silver-tone tamarind heel for a sculptural finish. A knotted bow adorns the toe, dousing the backless style with feminine charm. Show yours off with cropped denim and midi dresses alike to channel the London brand's coveted sense of contemporary cool.
