Ask HN: Do you use an uniform to code?

In my school, there was one day of the week, where we learnt for the entire day about technical programs (industrial mechanics, wood work, industrial design, automotive mechanic, systems, ...). Among the programs, I chose Systems to learn and the interesting part that I want to share was than the school had forced us to use a light blue lab coat inside of the computer lab.

That old concept makes me think if to dress up an uniform has an impact in the flow work.

Do you use any specific clothes to help you focus when you are coding?
