Just to be sure everyone is talking about the same game. SASS and CAS are two entirely different organizations with vastly different rules and CAS does require strict compliance with their dress code. SASS not so much.
When I was shooting, it was SASS here and they did require compliance with dress code. You could shoot the first match, but then had to join SASS after that to continue in the club.That club also required you be a NRA member, but that has since been dropped. I have an original family life membership there.
