/cgl/ - Cosplay & EGL

I had a very unfortunate situation in which a dress came in mail in damaged package, somehow get wet on the way from the seller and stayed like this for a few days until the package arrived... now it smells terrible (like mold!! Although no signs of mold on the fabric), and I have no idea how to get rid of this smell if it is even possible. To make it worse, this is a Holy Lantern dress and I am afraid to do anything radical because it can damage the flocked print. I asked the local dry cleanery and they refused to try because of the print and delicate materials... Any ideas?
