I am a boy. I feel cold recently and want to wear underwear when I go out, but the students around me basically don't wear underwear when they go out. Should I wear it?

Most people wear very little now. If you feel cold, you'd better put on some underwear. I have worn it for many days. If you don't wear it, your legs will get cold, and it will not be good for a long time. You should put on more clothes now, or you will catch a cold. This is not good. Those who need injections and medicine should put on more clothes. People who caught a cold in the Spring and Autumn Period were susceptible to infection. Now most people are beautiful and don't wear clothes, but it's better to wear more clothes for their own health, especially in winter, most people don't wear cotton trousers. It's really cold, and it's okay indoors, if they stand outside for a while. It will make you untenable and itchy all over. In this case, going out will be very painful. If you put on more clothes, it will be warmer. I didn't know I had to take an injection to look good. Not cost-effective.
