When is it appropriate to start wearing autumn clothes and trousers, and how often do you change them?

Autumn trousers are usually worn in165438+1October, that is, after the season changes, the weather is a little cold, so you can change them every two or three days, depending on what you do. If you often sweat, I suggest changing it once a day, such as the type of work on the construction site. If the work is comfortable, it is ok to change it every two or three days.
