Thought I would share this. I found this in my collection a while ago and have been searching to see if I can find anything like it. I have no info' save it is not home made. I'm thinking it is Organza, no idea what the fur is, no real idea what it is except presumably evening wear. No idea of age but thought I'd share it.
It's not a knit fabric? It doesn't have the crisp look of organza. From the photos, the fur looks faux, but you would know whether it's faux or real from feeling and seeing it close up.
I agree with Maggie, I am not seeing organza, but we do need a close up photo to help determine what it is you have there.
