DESIGNED BY MR PORTER. The navy worsted wool used to tailor Mr P.'s jacket is sourced from a British textile mill and for this latest collection, we've improved the cut and fit. This single-breasted style is designed with tidy notch lapels and detailed with functioning buttoned cuffs and a single back vent – both of which give it a bespoke feel. Wear yours with a knitted sweater and chinos, or alternatively pair it with the coordinating trousers. Shown here with Mr P. trousers, Mr P. sweater, Mr P. T-shirt, Mr P. Derby shoes.
