The shalwar kamiz was worn traditionally by Muslim women and gradually adopted by many Hindu women following the Muslim conquest of northern India. Eventually, it became the regional style for parts of northern India, as in Punjab where it has been worn for centuries.
Even highly educated women pursuing careers continue to wear traditional dress in urban India, although men of similar status long ago adopted Western attire. The forms of dress most popular with urban Indian women are the sari, the long wrapped and draped dress-like garment, worn throughout India, and the salwar-kameez or kurta-pyjama, a two-piece suit garment, sometimes also called Punjabi because of its region of origin. Whereas the sari can be considered the national dress of Indian women, the salwar-kameez, though originally from the north, has been adopted all over India as more comfortable attire than the sari.
Salwar/Shalwar: A pair of light, loose, pleated trousers, usually tapering to a tight fit around the ankles, worn by women from South Asia typically with a kameez (the two together being a salwar kameez). Origin From Persian and Urdu šalwār.
Kameez: A long tunic worn by many people from South Asia, typically with a salwar or churidars. Origin: From Arabic qamīṣ, perhaps from late Latin camisia (see chemise).
You can buy an entire three-piece salwar suit, or a two-piece suit that consists of either a readymade kurta or a kurta cloth piece, each with a matching dupatta. For these, you must have the salwar pants stitched from cloth you buy separately. A third option would be to buy a two-piece ensemble, consisting of the top and pants, leaving you the task of buying an appropriate dupatta, or using one you already own, or buying a strip of cloth and having it dyed to your desire. The end result will always be a three-piece ensemble, but a customer may start with one piece (only the kurta) or two pieces (kurta and pants, or kurta and dupatta), and exercise her creativity and fashion sense to end up with the complete salwar kurta outfit.
The salwar-kameez is a form of dress that has been adopted widely in Punjab and is now known in English as the Punjabi suit; J. P. S. Uberoi suggests that the salwar-kameez is an Afghani import to Punjab (1998 personal communication). Punjabi forms of dress are therefore constructs or inventions of tradition rather than having historical veracity.
The village's men and boys largely dress in sombre colours in the loose trousers and long shirt (shalwar kameez) worn across Pakistan. Older men often wear woollen Chitrali caps (pakol), waistcoats and long coats (chugha), made by Chitrali tailors (darzi) who skills are renowned across Pakistan.
the shalwar kameez happens to be worn by just about everyone in Pakistan, including in all of Gilgit-Baltistan.
What is common in all the cases is the wearing of shalwar, kameez, and dupatta, the national dress of Pakistan.
Muslim and Punjabi women—whether Muslim, Sikh, or Hindu—often wear the dupatta over the head to create a modest look while framing the face with color. When entering a temple, Hindu women might comparably use their dupattas to cover their heads. Though the dupatta is often made of flimsy cloth and does not actually cover the body, its presence implies modesty, like many of the outer garments worn by Muslim women that do not cover much but do provide a symbolic extra layer, ...
The Pakistani National dress worn by women is Shalwar Kameez. This consists of a long tunic (Kameez) teamed with a wide legged trouser (Shalwar) that skims in at the bottom accompanied by a duppata, which is a less stringent alternative to the burqa. Modern versions of this National dress have evolved into less modest versions. Shalwar have become more low cut so that the hips are visible and are worn with a shorter length of Kameez which has high splits and may have a lowcut neckline and backline as well as being sleeveless or having cropped sleeves.
