Yes and no :) "On-demand" clothing manufacturing is practiced today, in that fashions change rapidly, and in response, retailers produce what can only be described as "shitty quality, fast".

(Exacerbated by Chinese clothing manufacturers + social media - they're extremely effective at churning out extremely glossy pictures for what's about the lowest possible bar of quality)

That - "fast fashion" - is what gets discarded.

That's not the way forward. On-demand manufacturing that's more along the lines of traditional high-quality bespoke clothing could be an answer, but it would mean that the vast majority of people likely can't afford to wear the latest fashion all the time. And even if we can sidestep that problem through technology, wearing "the latest" itself is a huge part of the problem. If you have clothes that are only meant for a season, you'll dump large amounts of textiles.

So what's needed is both a move to higher quality, and a move away from "fast fashion". Given that the entire industry makes money mostly on "what's new and hot", this would require a significant cultural change.

Now, if only bespoke shorts and tshirts became a thing.

I’d happily pay a decent sum for a set of charcoal tshirts that fit me perfectly and last for a few years of daily use. Bonus points of I get to choose a fabric other than pure cotton.

They are a thing. Find a local tailor. (They often hide out at dry cleaners, but not all of them are good :) OK, that will be more made-to-measure than bespoke - the difference there being that bespoke comes with a master tailor who does a really exhaustive initial consult on what patterns work for you, what fabrics work best, what specific cuts to choose, etc, while m-t-m is more "we measure you, you get a standard tshirt". It'll still be lightyears better than anything you get in a shop.

I'd expect you'll be in the range of $100 per tshirt, +/-

And yes, of course you get to choose a fabric, that's the point of bespoke :) It's also the major cost factor. Depending on your taste, there are some expensive fabrics to have.

Get a sewing machine and start making your own clothing. I've been trying my hand at it and I've made a few shirts and pants I wear during the weekends. They still look a bit shabby and not decent enough to wear for work thought.

Just take your tees to an (alterations) tailor if you want the perfect fit. They can do a lot. One problem though: your body changes.

Good idea, actually. I’ll try a local taylor.

I imagine you could do this via a local tailor.

I read the linked sources and that statement is 85% of clothes disposed are sent to the dump and 15% are recycled. Not that 85% of what is produced is sent to the dump in the same year. Granted its all going to the trash eventually.

Not all textiles are made to be worn -- and plenty of those that are are children's clothes that are outgrown.

FWIW, these are at least shared by some people. More than half of the clothes my baby wears are used, sourced from Facebook groups for local exchange/givaways, and as she outgrows a particular size, we just box those clothes up (except for the few we want to keep for the possible second), and pass them forward to someone else in need.

That's not a correct inference. It might be that all textiles produced make it to people's homes, but people also throw away lots of old clothes. Another reason might be that some textiles are not made into clothes, and are used only briefly for the purpose they were created before being tossed.
