Does anyone make this style coatee?

Is it possible that the jacket is similar to a double-breasted jacket? It is possible to imagine a jacket where the right lapel (the one with the buttons) actually has working button holes. In colder weather, you could undo the right lapel, tuck it under the left lapel, and button the left lapel on the buttons you could see. When not that cold, the buttons could keep the right lapel from flapping about. Not really up on the history of doublets, but I was looking for a practical use of the buttons, or a least where the idea of the buttons on that side came from.
