I mentioned it at the end of this thread. Because it is–pretty much–a BTtF in 1990. And as for what was changed in the culture and fashion between eras was–pretty much nothing? I mean, Disney didn’t dig into the differences in media culture between the time periods like they could have, but the kids slipped into the past pretty much transparently, and even though they made a point of wearing different clothes, their normal clothes would have fit in just fine.
