Yes @augustlan very wrinkly too.
I once hand washed in cold water, a dress I had worn only once. It ended up at least two sizes smaller and a lot shorter. :-(
I have washed some 100% rayon shirts and not had them shrink, just get wrinkly.
I won’t buy rayon for the above reasons any longer. I’ve had very bad luck with Rayon shrinking and wrinkling and I’m too thrifty to spend money on dry cleaning.
