Bit touchy aren't you Martin 123? Are you a 'grow bag and gold bars' kind of guy? Personally, I completely understand wearing a flying suit when flying an old biplane or warbird, and certainly see the logic in wearing a uniform with gold bars in many parts of the world - it's what the natives expect the Captain of an aeroplane to wear, and does make dealing with officials easier.
However, a flying suit with gold bars looks odd - combine the look with a single engine piston and it just looks silly. IMHO of course.
