CAMERAS flash and a round of applause breaks out as a file of lissom models traipse through the crowd, testifying that fashion is alive and well in Pakistan. Such extravaganzas, organised on the scale of theatrical productions, have become increasingly common in the last few years. Indeed, several shows are held annually in Karachi, the country's fashion capital; but more recently Lahore has emerged as a parallel centre of style. Here leading names in couture like Neelofer Shahid of Meeras, Rizwan Beyg and many others present their collections before awed audiences who pay exorbitant sums. Recently, when Shamael, one of Pakistan's leading designers, held a show in Karachi, fashion enthusiasts doled out as much as Rs 10,000 for the best seats in the house.
