Wearing a Suit and The Oxford Comma

I went to a shiva yesterday for a friend’s mother.  It was in the evening.  A bit uncertain about dress, I wore a conservative suit and a tie.  When I arrived, I realized most of the people were more casually dressed.  A bit embarrassed, I mentioned to a friend that I felt overdressed.  He said, “Don’t worry about it.  You’re never overdressed in a suit.”

And yes, this does relate to writing.  Modern punctuation trends seem to be minimalist to the point that one is occasionally confused (as in “Let’s eat Grandma.”).  My tepid response to this trend has been to drop the series comma before ‘and.’  The editor says No … stick with the Oxford comma (red, white, and blue).  The publisher can always take it out.  But one is never overdressed in the Oxford comma.
