@iris Simple, satin clothing survives because it wasn't worn as often. People wore out the harder wearing clothing.That said, you didn't see satin used much until faster fashions took over in the late Victorian. This dress/coat is taffeta, which is much harder wearing, with satin trim. I saw a research presentation once on the history of a fabulously expensive green damask silk in the 18th century, worn by a wealthy woman who lived alone. She was still wearing scraps of that fabric, purchase in her 30s or 40s when she came into her wealth, at time time of her death. The dress was made over twice, then turned into a robe and slippers. I think at one point it was used to line something.By 1820, fabric was mechanized as getting rapidly cheaper, so you start to see dress cuts like this one that can't easily be made over. And satin that won't last.
