A navy single-breasted design offset by gleaming brass buttons, this wool blazer oozes a distinctly nautical vibe. The precise, smart silhouette of this military mascot will instantly upgrade any shirt and trousers. Work with this by opting for a classic polka dot tie in an equally dark tone and a tried-and-tested white shirt. For embellishment, all you need is a pocket square; go a little off-beat here with a wildly paisley piece in more shocking shades of cyan and scarlet.
