If I may,,,

There are so many people on this thread getting upset over the word "rules".

May I suggest we change the word in the title to "Conventions"

A convention is a set of agreed, stipulated or generally accepted standards, norms, social norms or criteria, often taking the form of a custom.

This is what we're really talking about here. We usually agree that some things are just wrong. We usually agree that some things are right or OK.
The entire "Kilt do's and don'ts" thread proves that.

If one person breaks a rule, and others agree that it is an improvement and begin to emulate it then it becomes an accepted "convention".

If one person breaks a rule, and we all laugh at him, then we have agreed it was stupid.

A rule, like a law, is not a rule if it is not enforceable. And as we all know there aren't any Kilt Kops. So there are no "rules" to be broken.

We all police ourselves. We make judgments of others and how they wear the Kilt. We then choose to follow, or not.

Over the last 200 years we Kilt wearers have agreed that a Kilt looks better with the Pleats in the back. We have agreed that a Jacket worn with a Kilt looks better if it is shorter than a Suit Coat. We have agreed that Spats & a Horse Hair Sporran look better on a Pipe Major than they do on the street.

The word "Rule" seems to be one of those button words that upsets the Kilt World. Just as the word "Skirt" seems to.
