You mention cheap synthetics, well I wear a kilt all the time, (more or less) and a "cheap" synthetic wears better than wool, cleans better than wool and is certainly more practical in a reasonable climate. I have a lightweight synth for when its really warm, say in the 30's and that is OK just imagine a "proper" wool kilt.
To get accepted as everyday wear then the garment has to be cheap and reliable enough for that purpose.
I am for one not after looking like a vintage scotsman, but a modernistic person who happens to wear a kilt.
I really do not think that you actually wear an original kilt either, but a substandard wool made and altered by way of so called improvments. Tell me I gather your colours are course faded ones, the wool thick, waterproof and scratchy, no of course not so yours is no different to mine, a facsimile of the original.
