my strategy is to load up on socks and underwear, rely on blue jeans and khaki shorts to fill in the pants category, and buy shirts as i go along. of course, i bring a nice outfit or two as well, but for the most part, i can go anywhere in china for 3 weeks with an 18" rollaway.

clothes in china are cheap enough that you can pitch them after a few wearings and not feel guilty about it. but, i still try to keep my own supply of socks and underwear because finding quality product can be challenging.
