I have been to only one funeral that someone wore a kilt. The kilt was in very subdued colors of a tartan that I have no idea what it was. He wore a dark blazer (?) with a grey shirt. It was quite nice and appropriate, as far as I was concerned.

And I agree that a lot of people today do not have the slightest idea of decorum. Their idea of what is appropriate dress and actions for different situations leaves a lot to be desired. Everything seems to be so very casual. I'm pretty liberal in most matters yet I am very bothered this pervasive casualness found just about everywhere. And now i see that I am not the only one.
