I've just been writing a scene with a lot of descriptions of clothes and it got me thinking: what materials are clothes and shoes typically made out of in the lost cities?
Given that elves are all vegetarians, I have to assume that they aren't on board with clothing made with animal by-products of most kinds. So leather is probably out as a material for shoes, which leaves me wondering: are elven shoes actually like, plastic? Surely that goes against their environmentalist principles. Or have they got some sort of advanced synthetic replacement for leather that's also biodegradable?
Similarly for clothes, I have to imagine that elves would not like anything plastic/that sheds microplastics. But also silk is out (given silkworms) and wool/other fantasy equivalents might or might not be out as they still rely on animals. Do the elves exclusively use cotton, linen, and other plant-based fibers in their clothing? What do they use for warm clothing, then? Because you can't tell me that a linen cloak is going to keep you warm for shit.
