Until we got the "Oscars", the long sleeved "winter" shirt had a collar that was turned under to mimic the short sleeved "summer" shirt with its V-neck. Adults, in long sleeves, had the option of wearing the appropriate necktie, of course with the collar out.
When I reached the point of needing new shirts, I continued to turn the collar under, but the Scouts with whom I was associated preferred to wear the neckerchief under the collar and complain that the collar covered part of the identification on the necker.
Last week my grandson got his first Cub Scout uniform and complained about the fit of the neckerchief, over or under the collar. I showed him the way in which I wear a necker, he tried it and liked the feel with the collar turned under and the necker smooth against his neck.
