I recall back when I was burning myself out as a kingdoms submissions herald ("No, a lobster is not going to be mistaken for a lozenge!!!"), our principal kingdom herald and founder of our Gaelic-named shire wore his real-world clan tartan--as a great kilt. Since he was a professional historian by trade (and a Laurel, and a Pelican, and the principal herald!), nobody argued, although there was considerable tut-tutting among the period fashion mavens who sailed like stately galleons in their Elizabethan gowns 'round every event. I'm a simple Sassenach by lineage and choice of persona, so I steered well clear of any such discussions.
