What should I wear when going to Hong Kong and Macau in September?

I don’t know if you are a boy or a girl. If you are more afraid of the heat, you don’t need to bring these. If you are thinner and more afraid of the cold, you still need to bring them, because the air conditioners in Macau casinos and shopping malls in Hong Kong and Macau are turned on. It must be quite cold. My wife is very thin and feels cold, but I don't feel it. At most, you can bring a jacket. If it gets cold, you can put it on. I don’t know where you are from. Macau and Hong Kong are also relatively hot in September. Generally, you wear short sleeves or pants, long pants or shorts are fine. Long pants are still quite warm.

Hope this helps you
