It's a pity, when the visual records will be so important.

I wonder if the priest here wears DJ and bow tie for weddings, as he does for funerals?

The easiest thing to do is hire a complete set of gear for the male section of the wedding party, as my cousin did - getting married in an 18th-century mansion, he decided to have matching historical costume and was resplendent in gold brocade. Cost much more than is sensible, though.
