Nicholas Kirkwood - Nicholas Kirkwood’s black Casati sandals are embellished with white faux pearls which are reminiscent of the jewellery favoured by the extravagant 20th-century art patron and muse, Marchesa Luisa Casati. They’re crafted in Italy from leather with slender gladiator sandal-inspired straps, then set on a small gold enamel block heel. Wear them to bring a ladylike end to a floral top and shorts in warm-weather months.
