Thank you Lisa.
As you have said, I am giving the technical deffinition of formal. My intent is to explain what formal is, for those who are interested is dressing correctly, and to belie the idea, so often put forth, that "formal" is whatever the individual feels is formal for him.
Formal has a clear and concise deffinition that is perhaps not to everyone's liking, but it can not be redefined, only ignored .
I hope this is useful to someone who wants the information.
