Maybe women want to uphold their culture more then men?
Personally i used to wear western clothes and nor feel more comfortable wearing abayah, i didnt ask/tell my husband for permission before i started wearing it.
actually i now wear shalwar kameese inside the house as well as underneath as i find it very practical comfortable and easy to wear, and it look sbetter then jjogging bottoms and baggy shirt, although during my childhood/teenage years i never wore it and wasnt expected to by family.
I have family who are the same, in fact some went against their parents wishes by wearing traditional dress, when the parents would rather they wore western.
I dont think it is because women have less interaction in this society etc so it is easier for them to wear traditional dress, as where i live you see women wearing cultural/traditional/ethnic dress in all jobs and roeles, and it is considered normal (east london).
i do agree there is a problem with oppression of women that spans cultures and traditions.
yes my husband does wear jeans, ive tried to get him to wear thobe but he doesnt want to, and guess what that is his freedom of choice, im not gonna oppress him by chucking out all his jeans am i?
