I've been on both sides of the CNC coin. Worked two years as a button pusher and when I started off I still thought it was basically magic happening inside the machines. I worked the night shift and "ran" a 5 axis that was programmed by the morning shift guy to basically run by itself 24/7. Never even got to do setups, just measured, polished, and washed parts, tweaked the offsets as dimensions drifted, and replaced tools when they wore out. Often had orders in the 1000+ quantity range.
Then that shop closed and I was hired by a desperate shop owner to be his sole CNC machinist in a more agriculturally focused industry, where different shit comes through the door every day and I had to learn how to constantly wing it and to get ready for surprises, with limited equipment and much of it falling apart. Actually it's a rare occasion that I even get a print or tolerances to work with. Usually just have to figure it out with trial and error. Never a dull moment.

It probably doesn't matter what you wear so long as you don't come off as a complete retard. People really need workers bad. Even if you don't exactly fit the bill you may end up limping the company along to the best of your abilities, better than nothing so long as you don't make a habit of breaking expensive things.
But everybody wears Carhartt so that's probably a safe bet.
