Some large shopping plazas have prices on par with the west (600RMB for jeans, 800RMB for shoes). You can find cool high quality clothing/shoes of the same styles by just going to a different plaza. In the open markets the clothes are very cheap but prices aren't set. I purchased a fake Gucci watch for 84RMB yesterday. The man wanted 105RMB. My friend said I paid too much and 60RMB would have been adequate.
I purchased cool shoes for 55RMB in a plaza TaoTao Shoe store. I purchased Pepsi jeans for 125RMB in a Pepsi store.
