Insane antique dress

Insanely stunning vintage dress and slip from, I believe, the 1940s Lace outer layer has a long train. Would be amazing tied up like a bustle!!! I believe the materials to be Satin, lace, tulle. Fits like an xs. Perfectly fits on my size 2 dress form. Please note. This gown is very fragile! Handle with the utmost care! No tag, but it really reminds me of a rare gunne sax Renaissance dress!
