The single breasted blazer is probably the most hardworking piece a man can own and also one of the easiest to get wrong. Too boxy and it looks like you borrowed it. Too slim and it dates itself within a season. The lapel width, the button stance, the way the shoulders sit – these things matter more than most men realise until they find one that actually fits properly and suddenly understand what all the fuss is about. We’ve been looking specifically for blazers that move between occasions without effort. The kind you can put over a shirt for dinner, wear with trousers to the office, or throw on top of a clean crew neck and have it look considered rather than confused. Navy, mid grey, earthy tones that photograph well in natural light. The pieces in here have the structure and the versatility to justify regular rotation. A good blazer does not sit in the wardrobe.
