Wearing another clans Tartan?

[Carlo]

We do love beating this dead horse, don't we?

I do believe that beating dead horses and making them into sporrans is a good idea.
Adding to that I believe it also is a good idea to come back to this topic from time to time since it is an important topic and sometimes I tend to write something not because it is 100% what I think but because I think that the answer to that statement might be interessting.

Father Bill is closer with his analogy on clerical dress, and we can extend that to any uniform of groups whose membership must be earned. These are items of distinction which signify that you belong to a group.

Clerical collars in Switzerland are only for catholic priests which confuses me to the point of who/what actually grants you the right to wear one (Not arguing Father Bill shouldn't wear one. I understand that there are some cultural and religious differencies that have historical reasons.)

To the uniform part a question I have. A uniform consists normally of diffrent parts. In my Studentenverbindung it is a cap and a 3cm broad "sash". The sash alone doesn't make the uniform and the cap alone doesn't make the uniform.
When it comes to highlandwear, at least with the regimental tartans, only capbadge and tartan mark you as clansman or someone from the regiment. Surely clanbadges are registered. Why aren't they only sold by the clan.
That way you would know who is or isn't a clanmember.
