On one of the Facebook buy/sell groups someone posted this kilt and I mentioned that it looked like it was made of cheap fabric and that the tartan looked off because the weft has a lighter dark block than the warp does

The seller got offended that I would even suggest that it was cheap and that’s just how the tartan is and that he got it from a kilt shop in Scotland. Then someone who supposedly makes kilts posted that she didn’t see anything wrong with the tartan either.

So I guess my question is, Rabble, are there any tartans you know of that are different in the warp and weft? Or is this just some tat that someone is trying to sell as quality? I’m not interested in purchasing, I just need the justification.
