The country club where we are having the reception has a rule about men wearing jackets after 5 p.m. I'm not sure how to pass this info on to my guests. Can I put "Jackets Please" in the lower corner of the invite?
This information should go in the invitation. Because guests will have a problem getting into the club without their jackets, you are doing them a favor by telling them about the rule. "Jackets Please" doesn't seem strong enough to let them know that it's mandatory. Consider wording it like this: "Jackets required by the country club." That way, your guests will know you didn't just decide that you wanted them to wear jackets.
