Let's first ask: what makes "suits" so professional?
When you really think about it, there is no good reason.
Scenario 1:
You're at a wedding in July in Arizona, where it is 110 degrees.
You wear a long-sleeved jacket as part of a suit.
You die of heat exhaustion.
So what is everyone going to think about that?
Are they going to appreciate the fact that you wore a suit?
The whole wedding would have to get called of because a dying person is lying unconscious indirectly because he wore a suit.
Scenario 2:
You're at a business meeting on the 53rd floor of a building.
All of a sudden, a fire starts burning and everyone must evacuate.
You must run down 52 flights of stairs wearing dress shoes.
You trip and fall since you are not wearing good shoes and break your ankle.
There is not enough time for anyone else to carry you downstairs, so you become a casualty of the fire.
In both scenarios, you have died because of wearing "formal" clothes.
Also, a big reason why people wear suits is conformity.
They see that everyone else is wearing a suit, so that means that I should wear one too.
The entire concept of conformity is stupid.
I am an ardent anticonformist.
Just because everybody else is doing something doesn't mean that you have to.
If everyone else was doing drugs, would you do it?
A normal person would say no.
Also, why are suits somehow "presentable"? What makes them look any good.
One should consider where one end of the tie points to?
Is that setting a good example for young children?
Do you want your kids to get STD's?
I don't know, maybe it has to do with this sexual selection business that I don't believe in.
Also, what if someone just can't afford to buy a suit?
This is a classic example of discrimination.
Why are you giving someone such a bad rep because they can't afford to buy something?
Finally, suits are just uncomfortable. This ties in with the safety issues.
In summary, this is the 21st century, and it's time to stop freaking out about what people wear.
