Clan Heraldry: What you can and can't wear and display

[StevieR]

Do the items in question carry the coat of arms or the clan crest? There is a difference.

Anyway, I recommend reading the following link, in case you are still not convinced.

and this particular extract sums it up nicely for me:

". . . A Lyon Office document states: "It is not only illegal, but a social crime of the most grave character, to assume and purport to use your Chief's arms without a due and congruent difference. Anyone who does so merely publishes his own ignorance’s, and lapses into bad manners". . ."
