All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.
A woman is allowed to wear whatever clothes she wishes, even if tight, transparent, or revealing, and there is no harm in that as long as such clothes are worn in front of her husband only and it is not permissible for her to wear such clothes in front of anyone else. Ibn Qudaamah wrote, “Ja‘far ibn Muhammad reported that Ahmad was asked about a woman wearing transparent and revealing clothes indoors in front of her husband and he (Ahmad) said, ‘There is no harm in that.’ Ja‘far added, ‘I asked him (Ahmad), 'What if she goes out of her house into the yard unveiled while there is nobody else besides her and her husband in the yard?’ Ahmad said, '[There is] no harm in that.” [Al-Mughni]
Although such clothes are usually worn by dissolute and immoral women, it should be noted that not all aspects of similarity are considered imitation. The criterion for the forbidden imitation is doing what is particularly done by those whose imitation has been deemed forbidden by the Sharee'ah. Zakariyya Al-Ansaari wrote, “Ibn Daqeeq Al-‘Eed underlined that the criterion for the forbidden imitation (of women) is associated with that which is particular to them in terms of its kind and appearance. The same applies to women imitating men in the same illustrated manner…” [Al-Ghurar Al-Bahiyyah]
Al-Haafith ibn Hajar wrote, “If we say that they are forbidden because this is an imitation of the non-Arabs; so it is for a religious reason, then this was their symbol at that time when they (the non-Arabs) were non-Muslims. Now, since this is not something that is peculiar to them, it is no longer related to them, then that meaning does no longer exist, and it is no longer disliked.” [Fat-h Al-Baari]
This is why when Maalik was asked about the ruling on wearing the burnoose (hooded cloaks), he clarified that there was no harm in that. People exclaimed, “It is worn by the Christians.” He remarked, “It is worn here [i.e. by the Muslims].”
This means that as long as these clothes are not particular to dissolute women and not considered a symbol for them, there is no harm in wearing them. For more benefit, please refer to Fatwa 163531.
Finally, it should be noted that you should not deliberately look at pictures revealing people’s ‘Awrahs (body parts that should be covered under the Sharee'ah) while buying such clothes. The ‘Awrah of a woman in front of other women is from the navel to the knees.
Allaah Knows best.
