What is the ruling on a veiled girl wearing a loose, wide shirt that covers or reaches the knee, along with loose pants?

There is no specific type of clothing required for women; rather, there are certain conditions. Any garment that fulfills these conditions is permissible for her to wear. Most often, trousers or pants do not meet these conditions. Therefore, it is not permissible for a woman to wear them when going out unless there is a long, flowing garment over them that conceals them.
