Nowadays, some think that a woman should wear only long skirts, while it is okay for men to wear pants. The problem is, I couldn’t find any Scriptural reason for this. If it is wrong for women to wear pants (and I don’t think that it is) then it is wrong for men also. If it’s okay for men, ergo, it’s okay for women. It seems rather arbitrary to teach otherwise, and I hesitate to tell husbands that we get the luxury of picking and choosing what is modest and what is not according to our own limited sensibilities. If we are arbitrary in this, we come up with all sorts of inconsistent rules having no biblical basis whatsoever. Then we expect those rules to be binding on others, when only the Word of God is binding.
Think back to the time of Mt. Sinai, and the giving of the instructions on how to run a godly community (the Law). What were the people wearing? All of them, men and women, wore, as near as I can tell, robes. So in a sense, everyone wore long skirts. When we were given the command not to wear clothing of the opposite gender (Deuteronomy 22:5), how could people tell what belonged to one gender or the other? One way, I suggest, to tell genders apart was long hair on the women, and beards with shorter hair for men. But this is not legislated for us anywhere. Another way to tell must have been style or maybe even color differences which were clearly masculine and feminine. The mere presence of long skirts (since everybody wore them) did not serve to differentiate between the genders. There is no Scriptural warrant for teaching that pants are related to morality or modesty one way or the other.
