For the past few years I've tried to buy socks, underwear and even T-shirts without any plastic in them.
Turns out to be extremely hard, borderline impossible in many countries (including US and EU).
It gets even worse if someone doesn't want to buy online and wants to find a local shop then the chances go even lower. I'm not I've seen an 100% cotton product in ages in a physical store.
If you wear more classic mens clothing you can dress pretty much 100% in linen, wool, cotton, silk, leather and various brass/steel buckles. 100% merino wool (winter) or linen/cotton/silk blend (summer) for socks, underwear and t-shirts. 100% cotton and linen for shirts and trousers. 100% wool knitwear, suits, formal trousers, jackets and winter coats. 100% leather shoes.
Not to mention the clothes themselves last decades.
