Ko-gal is NOT a sub-style and here's why :3

Ok this is gonna be a very short blog ⊙⁠﹏⁠⊙ BUT.. I see alot of people saying that ko-gal is a sub-style but it isn't. I've done ALOT of research about gal/gyaruo  and all the substyles and there is a lot of confusion on ko-gal. Some people say it's not a thing at all and some people say it is, well it is a thing but it's more like a lable for a age group. It usually for gals in high school. But ofc you can have other sub-styles, It's just what you call gals in high school/teens, it's kinda like the label "Chibi gal" (gals under 12yo). So it would be kind of weird seeing a 20yo wearing a highschool uniform and calling themselves a "ko-gal". HOPE THAT WASN'T TOO CONFUSING BYE LOVES💋💋(⁠•⁠ ⁠▽⁠ ⁠•⁠;⁠)
