That is commonly how rules get made in the congregations. They start as guidelines for people that are in Beth Hell or that are visiting. And then the hounders decide that it is fitting to extend those same guidelines for local boasting sessions and in field circus. Often, they even extend them for people that are home, or doing things that are necessary like shopping or work.
Notably, no allowance is made for hot or cold weather. In very hot weather, "brothers" still have to wear that collar button done up and their ties on. Some congregations even make a rule that the suit coat has to stay on no matter how hot it gets. Add a bit of running around like chickens with their heads cut off trying to reach people, plus having it be muggy as well, and it adds up to some lofty dry cleaning bills. Not to mention heat problems.
Cold weather poses a different set of problems. "Sisters" are not allowed to wear slacks, let alone thermals, in very cold weather. If they are doing street work, it can get dangerously cold for them to be standing around waiting for someone to hand a waste of paper to. Add some wind and blowing snow, and it gets potentially deadly. They can get severe frostbite, hypothermia, or stress sickness (and it's worse if they are not allowed to sleep). When it is down below zero and the wind is blowing hard enough, these policies can be almost as dangerous as the blood policy.
