regrettably, both self-respect (as can be seen by their attire) and respect for our Creator (at least in some churches and synagogues).... have gone far downhill
The church was likely Church of England (long before they went nuts) and the congregants probably a mix from the respectable middle class and upper class gentry. But even a working class parish would have seen people showing some self respect in their manner of dress. One interesting observation about the period is that, at least with men, one could often identify what social class they came from based on the type of hat they wore. Bowlers mark out middle class men, tradesman, middle rank businessmen and professionals. The guys with the toppers are gentlemen, defined in those as days not just by their manners and etiquette which the middle class also rigorously enforced, but also by possessing a safe income that allowed them to live a life of leisure. Often with more than one home and enough domestics to attend to all of their needs and every comfort.
It is highly doubtful that was a working class church.
