I personally like to decorate my uniform to the max!! and no.. it's not your ideal japanese uniform in any way, sure its v-neck sweaters with the logo but thats just about it.. before i started high school (i'm a tenth grader this year!! 2025) i searched up colors that would go great with white, navy blue and gray (the colors of my uniform)
I used japanese bow collars and those cute pleated skirts along with legwarmers and i even got brown loafers!!
imo just slap what you think looks good on there and don't worry about negative comments, your ideal fashion choice is way better then their ski masks or nike shoes/white shirt with leggings n big ass stanley/hot cheetos (very basic for them).
