This question came up when I was in Asia (Vietnam) for the first time and the cleaning service put by mistake a stranger's underwear in my clothes pack: Why is the underwear almost all over Asia made of some strange kind of plastic?
Yes, I see they write "100% cotton" on it, but it doesn't even remotely feel like European underwear.
And it's almost impossible to find the kind of underwear we wear in Europe.
Did anyone else ever experience the same? And maybe has an answer for Asia's plastic underwear?
