I recieved a communication the other day inviting me to an event. One part of the instructions described proper attire for the day. "Business casual" was the heading and then was detailed as sport coat and dress slacks, tie optional.

Ok, those in authority can make the rules, that is cool. But, then I started wondering, is this how I communicate?

Could dress casual be jeans, sportcoat & tie? What about dress pants, shirt & tie?
