People who don't really care about style

I feel like people my age have immaculate fashion sense, especially women, and since fast fashion is in rn every mf has access to stylish cheap clothing. It's something I'm kinda self conscious about, because there's this invisible pressure to look good. Went to the school bathroom today and heard a few girls shit talking me, ik I'm above all of this, they're teen girls, can't expect them to be mature,
But damn did it hurt. My family members always comment on this too. What's wrong with women just existing, it's great that some pay attention to their looks, just be satisfied by looking at those people and stop bothering us avg folk tryna get through life. I'll admit it, I don't have a trendy style, but it's not like I dress shabily or am unhygienic. I'm a clean freak, take good care of my skin and hair, what more do people want lmao. I think I'm the healthiest rn, but whenever I hear shit like "dress more feminine it suits you, you should wear some makeup" I wanna combust into flames and give them 3rd degree burns.
