If you look at most jackets today they have a blind button hole on the left lapel. This is a hold over from the days when jackets could be buttoned right up to the collar. Just as the boys in the photo are doing.
But the jackets are very cut-away, without (to my best viewing) either collar or buttons/buttonholes below the one that is buttoned at the neck. Altogether an interesting look but I wonder what kind of shirt you would wear under it today? Would you have some shirt collar showing -- seems uncomfortable to me to have the woolen jacket material up around your bare neck. Maybe that's why they look so unhappy
