Clothing in #Pokémon:

So a question I've started to ask myself is: What is clothing made of in the Pokémon World. Specifically before the invention of synthetic fibers. Ignoring the fact that real animals exist (they're too rare to be used for much clothing), it seems like most material has to come from Pokémon.
Looking around, I've found that wool is harvested from #Mareep (presumably also from #Flaaffy and (in the case that the option is available) Mega #Amphardos), #Wooloo, and #Dubwool.
