Do you have to wear shorts in PE can you wear sweatpants when it is hot?

You could wear sweat pants on a hot day to sweat more and when you sweat more you lose more weight. But wearing sweat pants on a hot day is not good for your hygeine. You could pass out while you are running or doing a sport in PE. You could get dizzy because your so hot and you fall down. So what i would recommend is to wear shorts so you can be more active and have a better hygeine.
