@Too-Old-For-This said in RL things I love:
Most of the companies I've worked for have trended between business casual and just whatever I feel like. Only one was business professional and man was I glad to get away from that one! The stuffy atmosphere was just UGH.
At one point, I briefly worked in a bank writing in-house data analysis software. I literally sat in an windowless office where we would never see anyone but our co-workers, and yet I was expected to dress as though I was going to be at an international summit. Skirt-suit, fancy shoes, etc.
I did not stay there long.
Where I am now, we can wear whatever the heck we want. One of our senior mechanical engineers—who does a lot of client-facing work—dyes her hair bright neon pink. One of the senior firmware engineers routinely wears rainbow leggings, shorts, and a t-shirt to work, and no one really looks at him twice.
I'm client-facing enough that I still try to dress semi-professionally (jeans and a nice blouse or sweater, nice shoes, etc.) when I know I have face-to-face client meetings. But when I know I don't? Hair back in a sloppy ponytail and wearing jeans, a Star Wars or Captain Marvel shirt (or something equally geeky; I may have a TeeTurtle problem serious enough that I should seek intervention), and sneakers.
So much better than the bank.
