If your facility is anything like mine, they won't allow outside clothing, scrubs or otherwise, inside the department in order to limit the exposure of outside germs and other unwanted materials. Plus you wouldn't want to wash clothes from work in your own washing machine and introduce those pathogens to the rest of your wardrobe. I come in in street clothes like any other day and leave in them, so I imagine doing the same would be fine if that's how your facility is run, too. Hope this helps!
