I have very good experience with this TaoBao shop in Beijing:

http://speedzone.taobao.com/shop/vie...d=33006457&v=1

mobile: 13371778773 (only in Chinese)
Location: BJ, 4th ring road north area

To find the location is difficult as it is in a Chinese neighborhood. Entry here, floor there, elevator up, corridor here, Apt there. Finally you end in a private apt. full to the ceiling with boxes. You will need a Chinese support. But the prices are reasonable and the quality satisfying. I bought several trousers, jackets, gloves and various other stuff there. I guess it is over production as the lady doesn't have all sizes of all item at any time.
