It is prohibited for men to imitate women and vice versa with regard to clothing that is unique to one’s sex, and the one who does that is subject to the threat of being cursed.

It is not permissible for a woman to ask her friend to shave her pubic hair for her, or to let her do that. If you do that, you will both be committing a major sin, and you will not be excused for that, because it is easy to find other ways of removing this hair, such as using the well-known depilatories, if you cannot use a razor. This is permissible in cases of necessity when one is unable to move, or if one is sick or insane and other cases where a man or woman is unable to shave the pubic hair.
