Most men who think they want a plain navy blazer actually want something with a bit more going on. They just haven’t found the right stripe yet. The wrong stripe is a costume. The right one is a blazer you reach for constantly because it does the work of adding interest without requiring anything extra from the rest of the outfit. We’ve been looking specifically at stripes that wear well in real situations, a dinner that isn’t quite formal, a weekend that isn’t quite casual, the kind of Saturday where you want to look like you thought about it without looking like you tried too hard. Chalk stripes, pencil stripes, wider bold stripes that work with a plain trouser and nothing else. The cut matters as much as the pattern, and fabric weight is what separates something that looks cheap from something that looks considered. These are the stripe blazers worth owning.
