Can you advise me if there is good shopping available in Xi'an? I am interested to know if it is possible to purchase clothes such as a Winter jacket or coat in American sizes ( Medium - Large). I will be travelling in early March and understand it will be quite cool so would like to know if I need to I can purchase a coat there. What is the quality of the clothes like? Are the styles modern and up to date? Where is the best place to shop for such an item?
