sorry ziggy, I've been trying to find out info on them myself. It doesn't help that I don't know anyone in Karachi, yet fall in love with their designs all the time! :(
^ They are apparently very secretive of their work and getting info on them has always been difficult. Plus I've heard that ordering from abroad is something they don't do?
I also love some of their stuff, but they just make it very hard for clients to like them...
It is practically impossible unless you know someone in Karachi who can act as your representative and go and talk to them. I wouldn't even trust a relative to do that job for me. Also you have to take an appointment slot to visit them, which I've heard are closed weeks before.
Hoping to go there next year if I can get to Karachi.
