Another fix is to have the skirts be, ya know, skirts. The private school I went to had a minimum skirt length of below the knees. This middle of the thigh length skirt is inappropiate for teenagers. Especially at school, more so a private one. You'd expect to see yansim's school uniform more in fetish stuff rather than an actual highschool.
Isn't this school supposed to be elite? Tangent: why is this school so animu if we are supposed to take this world seriously? I mean this school was designed by "god" (the tots perfect high school girl) and her dad (the CEO who wastes valuable talent to stroke his ego) so why is it so incompetent? The dress code is lax. Half of the school building is wasted space. Worst of all, there is barely any concern for safety.
I mean, in a country notorious for suicide, the roof railings are very low. In a school that is privately owned there are little to no security cameras. There is a literal gang of students hanging out by the incinorator. There's an incinorator which students have easy access to. The school is severely understaffed, as there's only one gym teacher, who also acts as a plaground assisstant. The pupil population is extremely small. Especially for the size of the building the school uses.
This isn't even going into the "dress" code which is lacking, especially for a japanese school. I mean, I might be wrong but, aren't the male and female uniforms rather out-dated.
