“The way in which to tell what is for men (i.e, their dress code) and what is for women is by the custom and what is suitable and what befits the two sexes and that which the religion has stipulated for them both with regards to their dress code.
Women’s beauty should be concealed from men at all times and they should not expose themselves to strange men. They are forbidden from wearing trousers, hooded cloaks, short dresses and so forth.
Women are also ordered to not raise their voices due to the fact that their voices affect other male’s hearts in public and this is one of the reasons why women are not allowed to raise their voices in the call to prayer. They should not make du’aa (supplications) or thikr (words of remembrance prescribed in the sunnah) out loud in the presence of non mahrams, nor do they climb Safa or Marwa (two smal mountains in Makkah). So the women are advised to cover their faces and hands from non-mahrams.
It is related in An’ni’hiya that men should have certain clothes which distinguish them from women and vice-versa: women should have clothes that distinguish them as women.”
If a woman wears the clothing of a man and it is tight on her such as around her body like that of some of men’s clothes, like tight sleeves, tight private regions and so forth, (then) indeed she has imitated him and she has brought the curse of Allaah upon herself (1).
If her husband does not prevent her from doing so, or is pleased with what she is doing, he has indeed shared in that curse, (as he has) aided her in such a sin and he will be sinning with her which is the opposite of what Allaah has ordered him to do. That is to have Taqwaa and he has also bee ordered to save himself and his family form the Hell-Fire, as Allaah The Exalted says in the Quraan:
“O you who believe, ward off from yourselves and your families against a fire whose fuel is mankind and stones.” [66:6]
(1) Ibn Abbaas said, “The Messenger of Allaah cursed those men who imitate women, and cursed women who imitate men.” [Bukhaaree]
‘This question was put to the Shaykh: Is it permissible for the woman to pray in tight fitted clothing?
The Shaykh -Rahimullaah- answered saying:
‘If the intent by the word ‘permissible’ you mean is the prayer accepted? Then apparently the prayer is accepted. And if the intent of the word ‘permissible’ you mean that it is no problem for her to pray like that, then that is a problem, because as you know that from the conditions of dress by which one must cover the ‘Awraah (the private area) regarding a man let alone women that it should not show the size of the ‘Awraah.
However, we do not have any evidence to say that prayer in this condition is invalid. But there is no doubt that with the second meaning that it would be okay for her to pray wearing tight fitted clothing, then this is not allowed, as for the prayer then it is accepted.’
Then the Shaykh -Rahimullaah- added by saying:
‘It is necessary that she wears above her clothing the like of an ‘Abayyaa, wrapping sheet worn for prayer and things similar to that.’
