I am not sure of title or author, but it was about a young woman, or older teens, who had been kidnapped/taken to this weird house and given names of fruit/vegetables- the main character was given the name “Olivia” or “Olive.” Other young women/teen girls were manipulated to believing their new identity. They were punished if they didn’t go along with the doll-like clothing, names, etc. (and for some reason, I recall their clothing and names were somehow related… maybe by color or pattern?), and I’m not sure how it started or ended, but I believe the “Olivia”/“Olive” character escaped. I think I read it when I was 12. It was terrifying and intriguing and probably why I love various crime & mystery, thrillers, and some of the more intense, darker novels (ex. ‘The Alienist’ and anything similar), whether fiction, based on a true story, or documentary/memoir.
Lost Classics of Teen Lit: Name That Book! 
I vaguely remember reading a book like this in the ’80’s. I think one of the girls was called Peaches? It was a pretty scary book, if I recall. Like, not actually meant for young people. I can’t remember much else about it either, but it might come to me later.
