This navy wool pinstripe double-breasted jacket gives a classic British look a modern twist. It’s cut from ‘Fox Air’, a high-twist open-weave fabric woven by Fox Brothers & Co. in Somerset, which resists creasing and breathes comfortably in warm weather. With sharp-looking peaked lapels, slanting flap hip pockets and real horn buttons throughout, this piece can’t help but impress. Matching trousers are available too.
