I'm going to say no. If you understand this era and its fashion, you'll note a girl about 8 wearing an adult day gown that wouldn't be appropriate for her age at the time in history. It's not revealing at all. She takes part in a séance.
I took one of the victims to be a victim of an unsafe botched (maybe forced) abortion, but this word is not used, and it's unclear at first. "Sliced up inside" with hemorrhaging.
