Marni's Pre-AW19 collection is inspired by Dada – an art movement that places emphasis on instinct and the child's intuitive way of creating – and includes an array of subversive wardrobe staples, including this blue chambray shirt. It's made with vibrant red topstitching which frames four flap pockets that are finished with pointed hems, then is offset with large white buttons. Style it with wide-leg trousers and chunky loafers to reflect the show's eclectic styling.
