In Karachi, there are LOTS AND LOTS of men’s stores that sell gorgeous sherwanis. You don’t need to go to Amir Adnan or Deepak Perwani because they are really pricey. Try Junaid Jamshed or Aijazz, their stuff is very reasonably priced. Go to Tariq Road, alot of nice stores there as well. Within 15,000 you should be able to get a nice one.
