Attan originated and still is main part of culture of Afghans (Pashtuns/Pakhtoons/Patans). Afghans whether they are in Afghanistan or live in other side border still they are Afghan/Pashtuns. In my opinion, when we talk about Pakistan culture, they are mainly under influence of Panjabi which similar to Indian. And overall Pakistani follow Panjabi culture, even some Pashtuns when talk they prefer to use a lot of Urdu/Indians with English words. When listen to a sentence of them, 80% made from Urdu/Indian & English words. If you look carefully in this video clip, the song is Afghani but one guy wearing two colour traditional dress which is not Pashtuns cloths but it is more like Indians. So, anybody try to represent the culture of Pakistan, they should fallow Panjabi culture whom they do not wear "partoog' instead they should wear "loong". Real Pashtun man shouldn't wear "kameez' one colour and "partoog" in different colour. That's all folks.
