Moral act

Hello. And a good signature
I study in a Hasidic synagogue where it says at the entrance, “Please observe the teachings of our rabbis and sit with a suit during study.” The thing is that more than half of the people sitting there are blabbering about the scripture and sitting without a suit. The question is, am I still obligated to this law from a moral perspective? I have seen that you have explained that morality is binding even though my individual actions have no effect. But does morality also oblige me to act according to the law even when the individual sees that the majority no longer obey the law? The other question is, let’s say I make it a point to wear a suit, because my group doesn’t have a suit at all (Mizrahi). My question is, am I considered a failure and should we look for another place to study? Or is there no need to be so strict? Thanks in advance.
