But how does wearing pants inhibit ones modesty? In fact, you're far more
likely to be covered up wearing pants than if you're wearing a skirt.
Your comment also suggests that women hold responsibility for whether
or not they are treated like sex objects. Noone should treat anyone that
way and the incentive for not doing so should come from within. A very
essential part of Judaism lies in the individual's struggle to perfect
him or herself. We should struggle with ourselves to see value in others
beyond their outward appearance the same way we should struggle to
perfect ourselves in other ways.
So why can't a woman wear pants?
