And Bunto Kazmi is based in Lahore ?
Bunto Kazmi is based in Karachi, but the point is irrelevant because it's far too late. There's no way she's going to take an order for July 2010 at this point; you usually need to place a bridal order with her at least 1 year in advance.
I agree with Maham, in that Nilofer Shahid is probably your best bet for a high-end traditional outfit in Lahore. However, she takes 4-5 months for most orders, so you would need to place your order SOON. Others to consider include HSY and Karma, though their outfits will likely be a little less traditional than Nilofer Shahid's...on the plus side though, there are a some HSY and Karma bridal outfits availble off the rack, which means that you could purchase them on shorter notice.
