I have often believed that there are two types of suppliers of things Scottish. Those who market to the unknowing newbies and play fast and loose with things like proper tartans (you can probably make your own list of such vendors if you're experienced) and those vendors who market to experienced customers.

Even L.L. Bean got the Air Force tartan right for their tartan shirts. If a shirtmaker can get it right you'd think a kiltmaker could...
