The Ruling on a Woman Wearing a Coat Over the Jilbab
Question: May Allah be good to you. I have another question: Is it allowed for a woman to wear a coat over the jilbab knowing that she will go out in a condition of necessity and severe cold?
Answer: “What is important is that a woman covers herself when leaving and cover herself completely. Nothing should be apparent from her by using any covering or clothing. What is important is that she covers herself. As for the details of the clothing, then this returns to the conditions of the women and to the need of the women. Nothing is prohibited except for the clothing which is for men. She does not wear the clothing of men. She only wears the clothing of women. The Prophet (ﷺ) said:
لعن الله المتشبهات من النساء بالرجال ولعن الله المتشبهين من الرجال بالنساء
The Messenger of Allah (ﷺ) cursed those men who are effeminate, and women who imitate men.
[Bukhari and Muslim]
So it is not allowed for one gender to resemble another. Everyone has a clothing. The men have their clothing and the women have their clothing. Yes”.
