Recommendations for polyviscose kilt

[Purgy]

Hi! I'm looking for a P/V kilt, I've done some of the research myself, but now I'm stuck, so I'm asking for advice/recommendation/help.
The recommendations I got so far from other members here, have mainly concerned shops in the USA, but given the cost of postage and customs costs,
recommendations for shops in Scotland or elsewhere in Europe would be more than welcome.
From the read threads, it seems to me that Marton Mills fabric has the highest quality. How to find out who is supplied by them, who uses their materials?
The semi-trad kilt from USA kilts was most often mentioned, so I’m thinking of buying something similar.
I'm a little skeptical, but certainly cautious, when I see the price of 50 GBP, and the opinions on the forum are that such material can not be below 90 USD.
Thanks in advance for all the suggestions and ideas.
