Can You Help Us Find A Dress Like This?

Hi,
My fiancee is having trouble finding a dress that suits her. One of her friends married in a dress that she would also love to marry in (she would marry in *that dress*, but she would prefer to retain the dress). The problem is, the dress was bought at some random goth shop (or something like that), and no one remembers where that was and the shop has probably gone out of business and there is nothing printed on the dress.
I have 3 pictures of the dress:

If anyone anywhere has seen such a dress (online or offline), please let me know where.

Thanks,
-Michael
