Itr is not at all uncommon, and certainly not a cuase for scandal. Clergy of many denominations wear clerical clothes like the black suit and the white round collar. Nobody has a patent or a copyright on that type of apparel. It simply happens. Many clergy don’t wear distinctive garb. Many do. There’s nothing “up” with that - it’s just a fact of life, and has been for many, many years. It has never been an exclusive “Roman” Catholic thing.
