Having gotten some Temu clothing as gifts, there are two main materials I've seen. One feels very much like a rough cotton, like the material harem pants are made of, and is mainly in the shorts/pants I've gotten. It's a cotton poly blend, and one is the material of the shirts. They're super stretchy and elastic, like a spandex almost. The pants and shorts end up with holes quickly as they rip near (but not on) the seams, and the shirts seem to actually last even if snagged because of how stretchy they are.

I wouldn't advise buying from them or anything, just saying that they're not exactly single use.

In the German documentary I've watched a few years ago it definitely looked like their business model was selling their customers insane amounts of cheaply produced clothing by encouraging them to change their outfit super-often, hence the term "fast fashion". They even pay influencers to promote this wasteful trend as "Shein hauls". And they steal designa from artists
