Someone did a search that led them to this blog. The search was “what Christian Bishops should wear.” I’m assuming that was the tenses, because it was by someone to whom English is not their first language, I’m guessing.
A Christian Bishop is the same thing as an elder, which is the same thing as a Pastor.
A Christian pastor should, in Western culture, wear a suit, tie, and polished shoes to every service.
I hope this helped.
