Indeed, it does! By construction, however, I mean the interior stiffening of the garment. In really, really, really good jackets, this is horsehair canvas. In poor quality jackets, it's a polyester material called fusible interfacing that has glue applied to it. The manufacturer then irons this to the underside of the fabric (the part the lining will hide) in the appropriate areas of the jacket.

I rather like the ring method of attaching buttons. I usually replace an Argyll's buttons with my own, and this method of attachment makes the job much faster. On my black Argyll, I've got reproduction Royal Provincials (name applied to the militias that fought for the King in the American Revolution) buttons!

On the tweed Argylls I used to own, both of Scottish manufacture, the buttons were sewn on as well. This is likely the case with J Higgins as the imitation stag antler buttons they employ are made to be sewn on.
