I went to highschool in Canada from 04 to 09. Most people when I was on grade 8 dressed casual in t shirt, jeans, hoodie, etc. Aside from that we had a gangster crowd we called the g units, cowboy preppy kids (not Alberta but my town had a rodeo vibe to it) who wore polos blue jeans and cowboy boots and all played football, the skater/stoner crowd, and a tiny goth crowd. Then grade 9 hit and like 30 to 40% of my school went emo. By grade 11 half the kids reverted back to "normal" clothing while the other half went into the scene crowd and later became hipsters.

Same haha. I do vaguely remember people looking like a much, much more toned down version of this, but yeah this shit was mostly relegated to Youtubers and Hot Topic models.
