No it's not lol you should look the part for a job you want
I feel like you'd be the guy who walks into a job interview dressed like stuff and gets mad when you get rejected
this is the problem with a lot of traditions. suit and tie = qualified is a tradition and it has literally no rhyme nor reason to exist anymore. suits used to be really forgetin expensive so the people who were wealthier/more committed to getting that job dressed in the garb. nowadays, you can even walk into h&m and pick up a suit for like a hundred bucks or so. probably less.
you've got to be a dumb-ass motherforgeter to think that i'm gonna come to an interview dressed like a forgetstick when i know sure as stuff that i'm gonna be rejected if i show up in jeans and a tshirt. i want the cultural norms and traditions to be abolished, but i'm still gonna follow them while they're around or go forget myself and try to get self-employed so i can interview myself in some got damn underwear
