What is appropriate for every day wear in Shanghai?

Hi! I will be in Shanghai this summer, and I have heard that they are rather conservative in dress and would like a little clarification. Is mid thigh too short for shorts? Is 2" below the clavicle too low for a top? I assume shorts/pants are okay for females though if not let me know please. I just do not want to appear rude or offend anyone! Also, what do those in Shanghai consider to be a female business casual look?
