Modesty isn't just about clothing, but it would be really nice if we could get the clothing part right
There is a famous book by the title "Beyond Good and Evil". One doesn't have to have too much experience to know that when men believe they have moved beyond good and evil, in reality, they are simply being duped by the adversary from seeing reality into an illusion that will entice them into the adversary's hands.
Moving "beyond" the core of the gospel is never really moving forward. It is always digressing. I have rarely heard someone dare to address modesty, and when I have, it is usually initiated by stating that the speaker or writer is pointing out that modesty isn't just about how you dress. And that is certainly true. There is more to modesty than the clothing one wears. A girl cam move her body in a provocative way, can use language that is suggestive, or use innuendo. She can suggest without being overt, and try to draw attention to her body as a means to attract men. None of these are modest. There are many aspects of modesty besides how one dresses alone.
But that core issue of how you dress is still the core issue. And we shouldn't listen to those who we sometimes run unto who, when they say modesty isn't just about how you dress, are really trying to excuse immodest dress altogether.
Sure, modesty really isn't just about clothing, but the clothing part is absolutely required
