Eh, personally I don't think uniform appearance is that big of an issue, to a certain point. If someone doesn't have a pressed uniform, it doesn't bother me. Now, someone coming to work with a stained uniform does bother me. It's one thing not to look your absolute best, it's another to look close to your worst.
I only press mine for special events or every couple of months. Of course, where we run (transport) most of our patients aren't even fully with it and the staff at most of the facilities couldn't care less. They just want the pt gone or put back in their bed quickly.
Now, my company is usually pretty good about replacing stuff. However, I did have to wear a pair of pants with a rip in the knee for about three weeks once. I was told I could go buy the pants myself and the company would reimburse me. But as I still hadn't seen the money from the last TWO times they said they would do that, I just waited it out. Got that "disapproving" look from one of my supervisors a few times, but trucks up always takes presidence over appearance, so I never got in trouble.
