Lengha shopping in Lahore or Islamabad

Hi everyone, hope you all are well :)

Me and my fiancé are fflying out to Pakistan in two weeks to do our wedding shopping. I am very confused about where to go to get my bridal lengha and my fiances sherwani. I will be there for 6 weeks in total. Which stores in Lahore and Islamabad should we visit?

I want something very similar to the Manish Malhotra lengha Deepika wore on the catwalk. (Navy blue, antique style). Is it possible to find this style in Pakistan? If so, where? Lahore or islamabad?

Any input would be greatly appreciated guys Xx
