Re: Why do Pakistan women dress like Arabs in America?
I've never seen a Paki woman wear Arab clothes in Britain, on the contrary I've seen many Arab women wear Shalwar Kameez.
If by "Arab clothing" you mean headscarf then that's not exclusively Arab, it's an Islamic thing, infact it's international, East European Christian women, Rroma gypsy women, some Medditerenean women, Sikh women etc. also wear scarves although not always in the same design.
My mom's English friend has some of the same scarves as my mom, only difference is my mom wraps them on her head whilst her English friend drapes them around her neck, it's quite an international piece of clothing..
If you are referring to the over-clothes (veil, gown, gloves etc.) that some Muslim women wear then that's international-Islamic, it's not really Arab/Paki/Indian clothing as such it's just outer-wear, women who wear them wear whatever they normally wear at home underneath.
Even if some Paki women do want to wear Arab clothing, so what? We live in a cosmopolitan world, cultures are merging. Why do Indian women wear Western clothes instead of Saari (even in India)? Nobody owns certain types of clothing, there's no such things as exclusively Arab clothing or exclusively Paki clothing anymore..
