I believe this dress is made up from the kit that was available in the late 1980s or early 90s. They come up on eBay every so often. I have seen at least two of them before. You could buy them brand new in a box, as a kit. I thought it was the late 1980s but Deborah at Antiquedress had one and she said hers dated from 1996, I think she said... It was a sort of comeback collection for Rabanne, but they didn't sell well (I think they were a few hundred dollars brand new then) The big difference between these late release ones and the older 60s ones is that the new ones are made up with vents at the side to allow for freer movement, and they are also usually shorter than the original 1960s version, which were usually either long evening gowns, or just above the knee. Also, I believe the original 1960s ones were tagged with paper tags, not incised or impressed on the back of one of the discs. The metal was marked this way in the 60s, but not the plastic.
