A warren of tailor shops offering custom made clothes, from tuxedoes to dress shirts to fake designer jackets and qipao. The prices are cheap but expect a lot tinkering afterward as your tailor will not be able to remake something as you like unless you tell her exactly what you want. The tailoring itself is average. Bargain hard and be familiar with the prices it would cost at a major retailer - even after bargaining, just getting a shirt from an H&M will be about the same price, but the H&M shirt will likely be much better quality.
