I like viscose a lot, but as all materials you get good and bad quality. Some items I have, are almost worn out / washed out due to bad quality
@Ingunn: Indiska has a lot of this quality and I agree on fast fashion (cheap, but not durable).
Other viscose items have last for years and years and are still looking good.
I prefer viscose before polyester because of it breaths and can easily be washed. Though not too good in cold temp because it is a "cold fibre". But I don't like polyester because it gets sticky (and I get a rash), do not breath and feels cold against the skin, not like natural fibres that sort of follows your body temp.
