Let me simplify this post.
When there is immodesty, men have to avert their eyes. What can women do to help the men? They can cover up.
This is partially right and partially wrong.
When you say that women are -helping men- that implies that the immodest woman isn't wrong. But she is. When she dressed immodestly, she already sinned. If she had wanted to help men, she wouldn't have dressed immodestly to begin with.
So the idea of covering up is two-fold -- first, to stop the woman from
continuing to sin by immodesty. two, to stop her from sinning
MORE by stopping the occasion of sin. thirdly, to stop her
being guilty of any sins that any man commits because of her.
This is why a woman who normally dresses immodestly lashes out when confronted because of her conscience, and she is forced to face her guilty actions.
A woman who dresses immodestly sins (potentially) 3 ways:
a. Personally, against God.
b. secondly, through being a temptation/occasion of sin.
c. thirdly, if any man lusts after her, she is responsible for those sins as well.
