How do you feel about the clothes in the cold and hot weather?

during the Chinese new year, I changed my hairstyle and cut my bangs. Ah, I didn't expect it to be so hot these days. I regret it very much, because bangs cover my forehead and I'm sweating! Today, in PE class, the students took off one piece of clothes, because the weather was too hot. I also took off my clothes. After a while, I felt cold, so I put on my clothes. After a while, I felt hot again, so I took off my clothes again ... I didn't know what to do. What hot weather! The hair I just washed the other day stinks again!
