My work's dress code
An actual uniform
Very smart - suits, ties, etc.
Somewhat smart - shirts, but ties aren't mandatory
Casual - I can wear anything that doesn't have holes/obscenity/football colours
Uber-casual - I can wear pretty much anything
I work from home, and I'm naked right now!
I don't have a job
