What should clergy wear?

[Redalgo]

Where is the "whatever the hell they want to wear" option?  Or I guess that should be the "whatever their congregation expects them to wear since they are paying his/her mortgage" option.

This. However, I voted for ceremonial vestments out of the options provided simply because I find it more culturally expressive and interesting than dressing like a businessperson or conforming to the unspoken public dress code of mainstream society.
