Should I be really pedantic and point out that tartan is the cloth the kilt is made of and not the pattern on it (that IIRC is the "Sett"). I recall, last year, seeing a "Jacobite" (1745) re-enactor in full kit (Broadsword, skein dhu, targe, dags etc.) all, I was assured (by another member of the society), carefully researched His Philamohr/plaid was of one sett, his tunic a second, his waistcoat a third (all of which clashed)[1] and these were matched with black and white diced hose and topped by a blue bonnet, he was certainly a striking figure (revolting taste to modern eyes, but striking). I wouldn't recommend the effect.
