If you want to look like a dogs dinner, then wear CS 95 (covered in various badges indicating your service, trade, command etc) finished off with an SD hat and flying boots. I can remember what my service and trade is, and would expect anyone else to work it out by the rank I wear and where I sit in my aircraft. As for berets - please don't start Beags off again - I seem to recall the forage cap had a nickname that was the vernacular for part of the female form, and suggested what one looked like when wearing it - I rest my case.
