What is the ruling on a woman wearing wide trousers, whether in front of other women or her mahrams, and why is wearing clothes not considered an imitation despite both men and women wearing them?

It is permissible for a woman to wear loose-fitting trousers that are neither revealing nor transparent in front of other women or her mahram relatives. This does not constitute imitation of men, because both genders share the origin of some garments like shirts and trousers, but the design differs. What is specific to men is forbidden for women to wear, and vice-versa.
