Taking its cue from Prada, M&S has embraced the Italian Riviera look with dip-dyed knits and Fifties postcard prints on full skirts, tops and bags. And, with Marc Jacobs very much in mind, there are cute key pieces such as wrapover cardigans in pastel yellow with ripped chiffon edging, tweedy, open-weave jackets with ribbon trims, full skirts in washed-out florals and sidebuttoned, cropped trousers that will no doubt be best sellers when they hit the shops on 5 January.
