I know there’s a trend of raw denim to not wash your jeans but back in 1863 that was the “trend” for all of your clothing. Women wore around 7-12 layers (an upgrade since the cage was invented to poof your dress instead of 15 starched petticoats). Since they had so many layers next to the body their dresses were more protected and they tried to never, if possible, wash their outer layers. If you were rich you’d soak a fabric broach in perfume and then attach it to your silk dress to keep yourself smelling pretty. Lovely.
