More granular data:
There are some garment making processes that can be automated most or all the way through, like knitwear and socks, but most will still be finished, assembled and/or packed by hand. Crochet is always human work.
Wool is pretty good to wear and when certified and from a good source, can be pretty sustainable if you wear it until it stops existing. This can take decades. Yarn can be recycled, mending is great!
There are fabric recycling initiatives, but the best option is to not buy it if you don't need it. Secondhand is more expensive than it used to be, but you can find older, better quality garments than the crap of today!
I do also have a bunch of laundry tips and opinions in me, but unsure if there's an audience for that. 😂
