My friend is a post graduate studying on international law. She tells that for buying clothes, Nanjing lu is not a wise choice. To be economical, Shanxi lu, Changle lu and Qipu lu are good place to go. Qipu lu is big, however, Shanxi and Changle lu areas has better clothes. Get off at the Nanjing Xilu subway station, you will get to Shanxi lu. I will go and have a look when I visit her next time. Hope I will not disappointed.
