Well the rules for hijab are derived from Qur'an, hadith, and the deductions of scholars, and you can find the subject of hijab discussed elsewhere here.

However, I do want to point out that, in many Muslim cultures, the clothing that is traditionally considered respectful for men is loose and long-sleeved, and there is also often headwear. For instance, shaykhs/religious leaders of most groups of Muslims today often wear loose clothing and a turban or other headgear. And, it is often considered indecent or inappropriate for men to reveal themselves extensively unless it is under special circumstances like maybe some kinds of work. To my knowledge, it is only in the modern era that it became fashionable for Muslim men to wear super-tight jeans and so on.

Anyway just a couple thoughts, you can find a lot on the subject of hijab on this website.
