If you didn't already know, Hoi An is popular for tailored suits and dresses. Tailor shops are quite common, and the clothing is really cheap in this city. But keep in mind that you get what you pay for in Hoi An, so be wary about the quality of the material used. BeBe, Yaly Couture and Bao Khan Sil are a few places that are recommended for high quality and reasonable pricing as well.
