What are some of the best books that offer an understanding of poise, mystery, and internal dignity in women?

I’ve recently been processing a new perspective on what makes a woman truly "classy" and "modest," and I want to find books that dive deeper into this. To me, modesty isn’t about being repressed or hiding; it’s the outward expression of a deep self-respect and a "quiet dignity."

I’m drawn to the idea of a woman who carries herself as a "lady"—someone who holds herself to a higher standard and whose "divine qualities" shine through her intellect and poise. I believe there is a massive amount of allure in mystery and restraint, where a woman is in total control of her image rather than letting it be defined by the desires of others.

I’m looking for book recommendations (fiction or non-fiction) that explore these themes. I want to read about:

Characters who embody intentionality and self-control in how they present themselves.

The idea that true allure is found in mystery rather than revealing everything for temporary attention.

A deeper understanding of "ladyhood" that is based on character, heart condition, and beliefs rather than just a societal standard.

I recently learned that for many women, the way they present themselves is a journey of healing from past insecurities or trauma, so I’m really looking for books that are non-judgmental but still celebrate the beauty of dignity and restraint. What should I read to understand this "graceful" perspective better?
