I remember and this is late 70s early 80s . My mom made all my clothes. ALL of them , we weren't poor , she had been a home economics teacher when that was still a thing. It was mostly because mom liked to sew and i had no choice. I went to a pretty middle class school system. I remember one day when the stitches on home made jeans gave out. Luckily I had a home made flannel shirt over a T shirt I could wrap around the blow out. By my freshman yr I finally got Wranglers with the big leather patch as Levis were a bit more, got them by soph yr. I was self conscious for sure and took some heat but never thought about a shooting spree. It would seem mental health needs addressed by schools counselors and maybe focused more on than pushing everyone in to college. Maybe if some one told the guy if he was being bullied, and no excuse for that, for wearing eyeliner that maybe he should quit wearing eyeliner? I would say 90% of my school lived in a sub division, I was in the 10% that didnt . I knew it and felt it sometimes and it probably hardened me up for life in the real world.
