Most men buying a blazer get tripped up by the same things. The shoulders are slightly off. The chest buttons at a strange angle. The lapel rolls when it should lie flat. None of these things announce themselves loudly but together they make a jacket look like it belongs to someone else. A blazer that gets it right does something different. It makes the rest of what you’re wearing look considered, whether that’s tailored trousers or a pair of dark jeans on a Friday. We’ve been looking specifically at construction quality, lapel width that isn’t chasing a trend it will regret in three years, and chest suppression that flatters without restricting. Single and double breasted both feature here because the right choice depends on the man, not a rule. We’ve also paid attention to lining, canvas, and fabric weight because those details separate a blazer you wear for a decade from one you quietly retire. These are the ones worth buying.
