I understand the ''dressing good'' part, but you don't have to wear a suit to be good looking, and why do you think wearing a suit = success, so many people wear suit everyday but never do shyt in their life, it's a myth, but this had nothing to do with reality.
There are two ways to look at it. If you've reached the top, or whatever you deem as success, then you can show up to work in pajamas or a suit, and no one would bat an eye.
If you haven't reached success, then dressing in a suit helps you get to where you want to go. It's not a huge effort or causation of physical duress to wear a suit. If it is, then you got issues. If you need to tailor your suit to fit better, then get it tailored.
If your reality is working as a landscaper or janitor and earning around $30,000, then a suit has no meaning. If you are working in an investment banking job or stocks and are pulling down over $200,000 a year, then wearing a suit is part of the deal and it matches the Rolex on your wrist. If you don't want to wear a suit, you are going to lose that $200,000 a year job. That's reality.
I work in a business casual environment. I don't have to wear a tie or suit, but I do need to dress appropriate in an office setting. That means dress pants and khakis and dress shirts or polo shirt. Kind of preppy.

If I walk into work protesting dress codes and march around in a speedo and halter top, I'm going to lose my job. Foolish people do not understand reality.
