is there school have different uniform? I mean it changes now and then

Korean schools have like 3 uniforms. One for summer which is usually shirt and trousers for boys and shirt and skirt for girls. Another one for winter which is blazer jacket on top of the summer uniform. Since they get snow in winter in some parts there, they are allowed to wear sweater or thicker fleece jackets on top instead of the blazer jacket but there are regulations on colors and styles, etc. Lastly PE uniform, a full tracksuit with a shirt underneath.
when are they coming back??
around late november
