I tried this for a while but honestly, I figured out, I am neutral colored athleisure basics person and Doc Martens (or on bad days, Medicaid grandma velcro neuropathy shoes) all day. Every day pretty much.
Now, I only buy Gildan heavy weight pieces and they're plain, boring, comfortable, durable and 100% cotton for $12 a piece maybe. I do not like fast fashion. Hanes has 100% stuff, too, but they tend to be less suitable for going out in public.
As for not being organic, I guess I can just wash them in white vinegar and hopefully eventually most of everything toxic will wash out.
It's just practical and helps my neuropathy.
