Hush Simone Slinky Cheetah Print maxi skirt - how to wash?

[lesgalettes]

I have the above skirt and have just looked at the washing instructions and it says dry clean only! I am not going to dry clean it, so wondered if anyone else has washed this skirt in the washing machine at a low temperature on a silk/delicate wash?

This is the skirt

I don't have this skirt but I do have lots of things that are silk or viscose and say dry clean only. I throw the lot in the wash on a cold wool/delicates cycle with a capful of Woolite, and have never had any damage.

It's 60% viscose and 40% rayon.
