Crafted from pure wool decorated in a subtle tonal check, this Parnell suit jacket from Kin by John Lewis will make an understated yet distinctive formal impression. Cut to a slim contemporary fit, it is fully lined and features a two-button front, notch lapels, flap side pockets, a welt breast pocket, four-button cuffs, and two vents to the reverse. Combine with the matching trousers, a fitted shirt and knitted silk tie to complete a sophisticated ensemble.
