Well here in SW OK we are mainly rural communities and the coachs hire their own umpires. Dress code for coachs is not heavily enforced for regular season games but when play offs come they all seem to adhere to the dress code ie no blue jeans. As I started and came up thru the ranks be brought to games thru a partner I asked about the dress code of coaches an was told not to worry about it if I wanted to call games. Don't get me wrong there are not any cut offs or ragged jeans when jeans are worn they are normaly starched and pressed and look neat.
