I wear normal clothes everyday but I have my safety shoes under my desk all times. I need to use them everytime I am in the lab because sometimes I have to handle heavy stuff, or everytime I visit the factory.
When I get to do experiments with materials, I wear a labcoat, otherwise I would get covered in silicone or other sticky stuff. I have to say, my labcoat is not white anymore, no matter how many times I wash it. hehe
