For long days at the office, opt for a fancy flat such as the Valentino Garavani Rockstud leather sandals in a neutral navy blue hue. They are made in Italy from textured calf leather with a razor-sharp point, three Rockstud-filled straps and an open back reminiscent of a mule. Pair yours with cropped trousers and a chunky knitted sweater for a daytime office look.
