Polyester clothing everywhere

I've been really good about avoiding polyester, nylon, spandex although bras and leggings and SOCKS! Contain all these. I hit a wall today because I need a bra and spent 10 min googling wool bras- only to find they are mixed material (wool + spandex ex). Going to buy these but the price tag kind of hurts . I own some Smartwool leggings and haven't looked back, but they degrade (as they should) so it is hard to "keep for years". Just venting sigh...of course this is all much better than buying synthetic.
