Allow PE kits in school during temperatures over 20 degrees

Background

I would like the government to make all schools allow students to wear their PE kits during weather over 20 degrees

Additional details

Students suffer a lot during warm days at school and they must wear a blazer a shirt and trousers and this does not allow ventilation in the body.This does not allow children to be comfortable and impacts they daily life at school it also may lead them to be less focused
