catholic school dress code

we're not allowed to wear skirts because some girls were hiking it up so now we wear LONG ass shorts. HELP ME.Then my mom wanted me to tuck my shirt in so i told her i couldnt without a belt because i cant without a belt(i think it was in the handbook) THEN SHE GOT ME A BELT so now i look like a mormon missionary with my KNEE LENGTH shorts, ALL BLACK sneaker vans, and braided BELT. LORD help me. I LOOK SO GOOFY. tho hit me up if u wanna join the mormon church ;)
