Thoughts on Modern Clergy Wear Styles?

Fun fact: clergy attire starts out as conventional formal attire, but gets "fossilised"; the clergy continue to wear the attire while the rest of the world moves on, so in time it becomes "clergy attire", because only clerics wear it. Then somebody objects that it's inappropriate for the clergy to wear fancy/distincitive/old-fashioned garb, so they rebase to contemporary formal attire, and the cycle repeats itself.

The vestments worn by Catholic, Orthodox and some Anglican clergy when celebrating the liturgy are based on the court dress of the late Roman empire — i.e. this is what people at the imperial court, and public officials, generally wore.

The formal attire associated with Lutheran clergy in Germany and Scandinavia involves a gown and an Elizabethan ruff because, hey, that's what respectable gentlemen wore in sixteenth-century Germany.

Anglican clergymen used to wear a collar and bands of the type worn by all professional men in the eighteenth century.

Even today, in an evangelical congregation in the US, you'll often find the minister wearing a dark suit and tie of a type that most of his congregation rarely or never wear, but that they all recognise as the formal attire of a man of authority and standing.
