Thanks for your guidance. I believe the fabric is a silk crepe. It's a deep red and will probably bleed but I don't think I need to be concerned about that. Before I dunk the whole thing, I will test wash a tail that won't show when I wear it. I've read that sometimes a garment is marked dry clean only because there isn't enough space to put all the detailed instructions for washing it safely. And they know some people will go and ahead and wash without reading instructions anyway.
