In China, you’re not supposed to show too much skin, so short skirts, shirts, and dresses are a no. But, long dresses, long skirts, jeans, and shirts covering shoulders and most of the upper body (minus the arms) is recommended. If you’re going for more a business setting, men wear dark suits, just like everyone else, and women wear business suits or sometimes dresses with high necklines.
People in China have pretty much embraced Western culture and wear many of the things other people do. But one again, showing too much skin is definitely frowned upon.
Hope this helped!!
