Paul Smith - Paul Smith's AW18 showcase was awash with vivid graphics in psychedelic colours – all inspired by French artist Edmund Dulac as well as 1960s and 1970s concert posters – and the tie-dye frog print on this black shirt is one of the hallmarks of the collection . It's made in Italy from lightweight cotton, with a button-fastening front and cuffs that feature the house's signature stripe as lining. Fits true to size.
