Historian Marc B. Shapiro writes:
Ahoti Kalah, by R. Avraham Arbel… Arbel is a great talmid hakham.[20] His book carries haskamot from mainstream figures, including R. Ovadiah, R. Neuwirth, and R. Nebenzahl. In the book, he explains the importance of the shawl, how women are not supposed to leave their home and if they must go out they should appear unattractive so that men are not drawn to them, and how it is absolutely forbidden for women to wear jewelry outside their home. (Recently, Arbel expanded the section of the book dealing with women’s tzeniut into a full-fledged book of its own.)
