I think if you want to wear one whatever. Nursing is a profession, so why would we hold doctors higher than us saying we don't want to look like we are trying to be a doctor, we do most of the work anyway. I am not trying to sound rude but I think that we should do what ever is in the lines of our practice and wearing a labcoat is not out of line (wearing an arrogant attitude because you have one on is). I understand the underlying unwritten social rules of fitting in but I would wear one if it lookes professional.
