Gloves weren’t Ron to protect from germs....they were worn to protect the hands from the elements. White cotton glove do not protect from germs...nor do kid gloves.
And considering some of the hats worn....those were fashion statements and nothing more.
Gentlemen wore hats and suits in those days too
Look at pictures of the crowds at baseball games in the 20’s/30’s/40’s. Almost every man in the picture is wearing a suit and tie.
