Miuccia Prada's collections have been described as cerebral, shocking and austere, and they are always beautifully designed. The label is a firm favourite with the A-list party set, who invest in the jewel-toned satins, the nipped-in pencil skirts and, most of all, the totally wearable angular dresses. Layer up with silk blousons and feather-light merino cardigans, accessorised with one of Prada's signature nylon backpacks. This is serious chic at its sartorial best.
