How will the people around you react to you using a suit? If it's badly, you are as much forced to wear a certain kind of clothes as the GP was.
Anyway, just because there is a dressing code, it doesn't mean that the culture normally associated with it dominates. Those are two different things, where one is a huge problem, and the other mostly irrelevant. It's always better if you react to problems that are rally there, instead of noisy proxies.
Different people can value these rules in different amounts, and to your point, I didn't value "what I'm wearing" as much as some other people do, so I get you.
A bunch of suiting trends come from this. Suit jacket with ruined pants? Now it's a blazer, so, casual wear. Handmedown worn 3-button suit that you're wearing casually at college, with the top button pretty much permanently unbuttoned? You've just invented the 2-roll-3 jacket style. And so on.
We've replaced this behavior with simply having all our clothes be disposable-cheap. Mending a hole and adding patches to keep wearing something's not really worth it when it cost $20 to begin with.
To defend myself a bit, though, most conversations I see around this topic are referring to comfort.
