Wear down jacket from June 165438+ 10 to the middle of 10 every year. It's better to buy down jackets here. When I go to school at this time in March, the temperature is warmer, so it's almost enough to have a thick coat. April is a thin coat, but the temperature is changeable at this time, so you can use a thick coat with a single coat. Pay more attention to the weather forecast of mobile phones ... since May, it's basically a single coat in the morning and half sleeves at noon.
