Burqa most definitely not woven in the Pakistani fabric as much as it was during Islamization and allowance of Refugees.
You say 1400 years, but if you read up on it, that shuttlecock Burqa dress goes back beyond that but only in the region known as Afghanistan.
And going back 1400 years, it was a dress in Middle East mainly.
Bro with all due respect. Pakistan itself did not exist 100 years ago. It was made for Muslims & so yes "islamization" took place sooner or later. What is the problem with trying to follow Islam better? Don't you want to get into heaven?
Bro if you have a problem with a specific style then there'll be another style such as the niqab where you see the eyes which is not relevant to Afghanistan. The veil does have backing from Islamic texts. There is only a difference of opinion in regards to whether it is obligatory or whether it is recommended
