Recommendations for polyviscose kilt

[Purgy]

Steve, thanks for the answer, but my dilemma still exists.
Please do not interpret the continuation of this message as any kind of advertisement or negative criticism, I will only show by a concrete example what is bothering me.
I hope and believe that clarification and possible answers will help other members as well.
I read the rules of the forum and nowhere did I find that the names of the shops should not be mentioned, if I missed it I apologize in advance and I will understand if this post is deleted.
So, I learned that the Semi-Trad kilt, 5 yards, from USA kilts costs 160 USD, Clan by Scotweb offers Essential Scotweb Casual Kilt 145 USD, 5 yards, and The Scotland Kilt Company offers Men'sSKilt - POLYVISCOSE Party kilt - 40 USD, 5 yards (So, I learned that the Semi-Trad kilt, 5 yards, from USA kilts costs 160 USD, Clan by Scotweb offers Essential Scotweb Casual Kilt 145 USD, and The Scotland Kilt Company offers Men's Kilt - POLYVISCOSE Party kilt - 40 USD. The "problem" is that both kilts from Scotland are listed under the materials: polyviscose. Experience teaches us that when something sounds too good to be true it is usually not true. But if one company sells acrylic material as polyviscose, who guarantees that another company with the same name is not even more “capable” so acrylic material sells 5 times more expensive, I hope you understand my dilemma. I am a new member of this forum and generally new to the world of kilts, so I do not recognize Pakistani or other companies because again they both boast of tradition and origin. I hope I’ve been able to clarify the problem at least a little bit, and I’m probably not the only one with that question either.
