As a seamster and a historical fashion nerd, I'm going to add something here. If we were to move back to hand making stuff, and thus each item being made for much more money but being made to last ... we're going to have to change the way we wear clothing.
One of the major reasons that people wore so many layers in the past was because each item of clothing was precious. A related reason was that washing clothes was very labour intensive, but even without that being true, washing still provides minor damage to clothing from abrasion and so on; it's why wearing polyester and other synthetic fibres shed microplastics into the water.
If you want clothing to last, you put layers between your skin and that clothing. People wore linen undergarments, and later cotton, and these layers would soak up sweat and skin oils, keeping your outer layers much cleaner, so the outer layers might need spot cleaning occasionally, rather than proper cleaning once each wear. You'd expect the under layers to wear out faster (although I understand that historical linen, rather than the poorly made mechanically produced modern linen, could take a fair beating), and the top layers would last – ideally – for years. Long enough that they're not discarded, but instead remade into something new, either for yourself (by changing trimmings or swapping bodices or similar changes) or for a younger member of the family.
(If you were wealthy, a largesse you might provide servants would be to hand down your gowns or suits when there's still a bit of wear in them, rather than just discarding them when you wanted the newest fashions.)
So: underwear that covers a lot more skin than a G-string and bra, and fewer items of outer clothing, which are treated more carefully than the way we currently do.
It’s a very different approach to clothing, both a change of how we wear clothing and how we think of owning and acquiring it.
