So what actually is going on with link closures on dinner jackets, e.g.
Is it functional button holes on both sides of the jacket, closed by non-attached buttons connected by a cord like quasi-cufflinks, or is there a button sewn on the right side of the jacket as normal, and a second button linked by a cord to close the functional button hole. If the latter, what is one meant to do while wearing the jacket open? Let the button dangle? Tuck it into something?
Two button holes with a glorified cuff link between them.
If you go over to the black tie thread I will post pics of one of mine.
