Moreover, people would like to take off the thick winter coat to showcase their colorful attitude towards the warm spring sunshine. Here, an annual fashion feast in Beijing not only could provide you a visual inspiration of trend, but also would tell you what’s the most "in" factors in the coming season.展开更多
