Most suit jackets look like they belong to someone else. The shoulders sit slightly wrong, the chest pulls when you button it, the whole thing reads as borrowed rather than owned. Structured construction is what changes that. A jacket with real canvas in the chest and a shoulder that is actually shaped to carry the garment moves differently, sits differently, and makes the person wearing it look like they know what they are doing. That matters whether you are putting it over a full suit or wearing it with trousers that have no relation to it. We have been looking specifically at jackets where the structure serves the wearer rather than fighting them, where the lapels roll naturally and the chest does not go concave the moment you sit down. These are not costumes. They are the kind of jackets men keep for a decade and reach for without thinking. That is exactly what structure is supposed to do.
