I'm very confused on the "shoujo girl" style, I used to call it himekaji but then people said it's not himekaji, it's shoujo girl, now yall are saying it's disrespectful to call it shoujo girl. I swear I remember that himekaji was a more casual and less extravagant version of hime gyaru, doesn't kaji literally mean casual, hence hime(hime gyaru)-kaji? correct me if I'm wrong. and lastly shoujo literally means girl in Japanese, calling it shoujo girl means "girl girl"?
