You're honestly making the argument personal. There's nothing inherently wrong with wearing a suit. If people are content, comfortable and happy wearing what they have, then why bother all of your ad hominem comments. We don't need reminders that the 20th century has created the "cargo pants."

We know that cargo pants exist, but maybe they prefer a suit?

I've acknowledged your point no need to berate everyone down the line as well =/

Cargo pants are baggy and in my experience tend to get caught on furniture.

(Not to mention they make you look like some sort of ex-marine wilderness survival nut or something)
