Hi Vasha! How are you?!
Here's a link to a discussion about washing costumes from a few months ago, including links to other discussions.
to dryclean or not to dryclean
Handwashing seems to be the consensus, but I'd be curious (and by curious, I mean really brave) to machine wash a costume in a pillow case. I wonder if anyone has tried it?
I'm all about the vodka and water spray too after reading about it on bhuz.
