What is the ruling on wearing wide trousers in front of women and Mahrams for learning to swim, knowing that they become tight-fitting to the body after exiting the swimming pool?

When a woman swims in trousers, they cling to the body and reveal the size of her limbs. This is makrooh (disliked) because it defines the awrah (intimate parts) and describes them. It is haram (forbidden) if it shows the color of the skin. Therefore, women should avoid swimming in trousers in front of mahrams (unmarriageable kin) or should wear an izar (wrap) or a dress over them.
