Baffled as to why flying suits should be an issue to anyone other than aircrew, I personally would love to saunter to lunch in the Officers' Mess in my No 1s (they do look very smart esp. with wings and medals).
The truth of the matter is I don't get time for lunch break, and what time I do get to cram some 'high energy' (another thread methinks) rations down my neck does not allow me time to get changed into something others find appropriate.
The issue of badges seems strange also, in my experience FJ Sqns have a standard set of badges which everyone wears, usually in the form of a aircraft type (worn after P1 qual) a Sqn badge (post CR) and a name badge, with wings. On ops some guys wear a Union Flag patch, but then again war-suits are sanitized anyway.
