Yes. They should have atleast went for early 2000s. The whole talk on kim's attire looks stupid since she is fully covered and the drama is set in karachi. I am pretty sure girls there roam around in jeans and tshirts.
We have seen girls in pak other dramas wearing such outfits, so yeah it's normal. Also who wears such old fashioned barkhas. I guess writer ny yeh drama 1990's ky according hi likha hoga.
