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. 😂
Laundry tips and opinions which were requested:
Using fabric softener will make cotton feel clammy and greasy, and give it a mildewy smell. Fabric conditioning helps with staticky plastic fibres but isn't necessary for natural fibres! Just wash without. Never put it on towels, it stops their absorption powers. You can use a little bit of vinegar instead of fabric softener, it will have a mild smell when wet, dries odourless.
Line drying is less wear on clothes than dryer but live your life if you have no place to dry them!
Bedding needs to be washed super hot occasionally! Towels, too!
If your shirts smell terrible because you've been sweating into them, soak them in the sink with a cup of vinegar in room temperature water, rinse, wash normally. This kills a lot of mildew and helps break apart organic residue.
Liquid laundry detergent is silly! Just get detergent in powder form, you're spared the plastic bottles and no heavy liquids are ferried around.
Soap nuts are great if you're allergic to everything but soap nuts. They're not even nuts and are compostable!
A lot of the washing instructions are LIES. You can literally boil 100% cotton and it's fine! You'd be amazed how much dry clean only is not! Polyester and cotton will be just dandy in 60 Celsius - the manufacturers play it safe because some dyes fade in hotter temps. Cheaply made clothes may shrink, but if it's stinky, take the risk!
