Viscose jersey is ok, it makes lovely cool t-shirts and drapey tops, but the woven fabric creases horribly unless it is mixed with something else. It's worse than linen. I do wear quite a lot of linen, it is so cool and comfortable that it spoils you for anything else. However, cheaper linen is the stuff that crumples. I have some ancient expensive linen skirts that cost a small fortune way back when I had more money, and they crease very little. I bought a navy linen blazer 20 years ago in Chicago in a sale, reduced from $200 to $20, and it is brilliant. Also thick silk shorts, now sadly rather too tight. They know how to dress for muggy weather over there. I think our fashion buyers are at fault here.
