Actually, the above photo confirms what happened to those railings and other photo's on here show the church yard sans railings...just stubs remaining. Waist coats have disappeared pretty much now....they hid your braces. Yeah the one fella has his top button undone to relieve the 'after lunch' waist strangulation. Yeah, you have to put up with that all of the time with a belt. Slacken off a notch and yer pants will fall.
Come to think of it I can't seem to remember belt loops being supplied on pants but bracer buttons were. Later an elasticated waist band was supplied with an overlapping clasp on the front and adjusters at the sides....a couple of buttons worth. I seem to think that this did the job but can't remember if bracer buttons were included for security. Now, here, it is belt loops only. Bracers have the confounded squeeze clip which don't work very well.
An improved arrangement would be to locate belt loops better so that leather bracer thong's could pass through, perhaps.
