To digress, Now I'm looking at https://www.reddit.com/r/Visiblemending/ with interest. Seems Reddit environmentalism is endorsing long lasting clothing and keeping them alive longer.
There's a reason those are largely gone - retreaded tires have been the cause of many accidents and blowouts over the years...
Master tailors who create bespoke clothing and work with very expensive wool fabrics may still have a reweaver that they use. It's only economically sane if one is dealing with suits, for instance, that start beyond $2000.
They aren't cheap and I really like their work, but I don't think they're the sort of place that people travel to buy from. So I imagine other tailors offer it.
