I am in independent practice, and fortunately dont work in a hospital. I wear normal clothes, because I can do occupational health work as well. Clean jeans, T's, Shirts, sweat shirts, whatever...
In hospital practice I have always understood the key issue to a uniform is preventing carrying infection, and capability to be washed at high temperature to kill bugs. So I would have thought this question is largely hypothetical because it depends on where you work.
What I HATE is seeing ward staff wearing work clothes in the street. Get changed at work, and leave ward clothes at work, carry work clothes home in a bag, and wash them hot, hot hot.
