I'm sort of embarrassed to post this question, but my husband is driving me crazy...so here goes.

We are taking our first trip to China later this month and my husband is stressing over whether he will feel comfortable wearing shorts during the day in Hong Kong, Shanghai, and Beijing.
We live in Manhattan and it's perfectly fine to wear shorts here. He is concerned that there are cultural differences that will make his leg-displaying attire offensive or awkward.
We aren't talking about gym shorts or cut-offs (gross) here, but rather J. Crew or Banana Republic shorts.

Please humor me and let me know your thoughts.
