In Chinese business culture, conservative suits and ties in subdued colours are the norm. Bright colours of any kind are considered inappropriate.
Women should wear conservative suits or dresses; a blouse or other kind of top should have a high neckline. Stick with subdued, neutral, colours such as beige and brown.
Because of the emphasis on conservative, modest, dress in Chinese business culture, flat shoes or very low heels are the main footwear options for women. This is true especially if you are relatively much taller than your hosts. High heels are acceptable only at a formal reception hosted by a foreign diplomat.
Men should wear suits and ties to formal events; tuxedoes are not a part of Chinese business culture.
Jeans are acceptable casual wear for both men and women.
Shorts are reserved for exercise.
