You have to be able to determine the quality yourself.

Find these things at actual boutique retail locations which are rather hard to find, or individual manufacturers direct to consumer website, and to find those... I don't know, it's not easy.

I think I somewhat know how to do this, i.e. feel a fabric and gauge its thickness and weave. What I don't know is how to search for it. What do you filter to get the thicker, densely woven cotton like polo shirts used to be made of in the 80s, instead of thin see-through half synthetic stuff so common today?

Wondering if there are technical specs for this like there are e.g. for paper with their "24 lb paper" etc.

You probably won't find it unless you do a lot of work to reach out to industry contacts and are willing to cough up a lot of money.

The market just doesn't exist, most people are satisfied with Costco/Uniqlo/H&M/Old Navy clothing for 95% of their needs, and maybe Lulu/Nordstroms for something a little more fancy.
