Ooh I have a story for this! So my mom and I went to the same middle school (also high school) and at one point when I was in eighth grade I got in trouble for violating the dress code (this was ~2009). They said my skirt was too short in spite of the fact that I’d worn it before (their actual problem with my outfit was that I was wearing black lipstick but that wasn’t actually against the rules). So they went through the rigamarole: called my mom to tell her to come bring me a change of clothes, make me wait for her in the office in spite of the insistence that the problem with my outfit was that it was distracting from my studies.
Them having to call my mom for this is perhaps the best example I have of the phrase “you got the wrong one”. Not only had my mother attended the same middle school as me, but she had actually been dress coded in eighth grade as well, for wearing pants. (This was ~1969). She’d actually planned it purposely as a protest. The dress code didn’t allow girls to wear pants, and she’d had a custom pantsuit made—classy, good quality, well suited to any class president even if she was a Negro—and she wore it to school one day I think after mid winter break. She didn’t make it past first period before she was called into the office. Admin called her mother, who noted that she didn’t have an issue with her daughter’s outfit, so in order to reason with her, they called my moms friend’s (white) mother—one with a lot of pull in the pta and the wealthy neighborhood that fed the school—to try and convince her to side with them. This backfired spectacularly, as she also didn’t have a problem with the suit, and they were forced to drop it and, within a month, change the dress code, lest all the wrath of the Laurelhurst mothers reign down on them.
My mother is the reason Seattle Public Schools dress code allowed girls to wear pants, & she was very excited to bring this up when she was called to the office about my skirt which, needless to say, I was allowed to continue wearing. SPS dress code allowed for students of all genders to wear pants from ~1969 to ~2018, at which point the dress code was eliminated from the district entirely.
