Thanks for your answers and the links to the previous threads, (must get the hang of this search thing) well I think I have found my answer.
Maybe there is a badge that could be worn on the suit, maybe I should market one, The inscription could read something like
"Its a flying suit whats the problem?!" or "This suit is here for my protection" or similar.
My flying club instructors are all for it and think that more people should wear some form of protective clothing when flying. So for now it will have to be the ex RAF ones but will try the other companies mentioned when these need to be replaced.
Thanks again.
