Long sleeves are too hot and short sleeves are too cold. How to wear them in the season with large temperature difference between day and night?

Put a long sleeve over the short sleeve, and put it on when it's cold. Take off your coat when it is hot.

It's the same here in early autumn. It's cold in the morning and evening, and hot in the afternoon. You can wear short sleeves, just like summer. But it's very cold at night, and sometimes it's windy. Wearing short sleeves is simply cold and windy. It's cold in the morning, so it's better when the sun comes out. But if you wear long sleeves, it will be hot at noon, and if you wear short sleeves, it will be particularly cold when you go out in the morning. So the best way is to wear short sleeves and long sleeves when you go out in the morning. Take it off when it is hot at noon, and then take it out at night when the sun goes down and the temperature drops gradually. It's cold. Take it out and put on your coat. This is the best way. Change it over and over again, saving the trouble of changing clothes.

When I was young, there was no such thing. As long as it is autumn, parents are not allowed to wear short sleeves, and all of them are replaced with long sleeves. Protests are also invalid, because parents are afraid of catching a cold, and parents who turn around feel trouble. So I can only wear long sleeves for one day, even if it is hot. Later, when I was in junior high school, my parents didn't take care of it every day, so I was left to dress myself. Although it is cold, I will ask you to change your long sleeves and put on more clothes every day. Don't catch a cold when it is cold. So some students still wear short sleeves. Although shivering with cold in the morning, I still don't change my clothes. Most of them are boys, which is more troublesome. They would rather be cold than change clothes twice a day. Students who are afraid of cold wear long sleeves and sweat in physical education class. So the more autumn comes, the more clothes are divided into two levels, some are particularly cool, and some are fully armed like winter. But now, the dressing style has changed a lot, and many people like it. It is easy to solve the problem by extending the time of wearing short sleeves and putting on a coat outside.
