FWIW I do wear period kit of 1942 desert era when with the appropriate LRDG (a unit disbanded at end of WW2) vehicles as part of a display or to enhance the vehicle era/history. I do like to see drivers wearing period kit or variations of instead of the afore mentioned cords/jeans, anoraks etc. I don't like the re-enactor side of things but each to their own I suppose.
As a Para of 30 Years (Now logistics last 5 to present) I do take offence at all of those wearing wings that they have not earned, as stated in earlier post re after doing P Company etc. On my period uniform I wear my wings (I am an APJI) and my current rank but suppose as I have came all the way up from Pte I could wear any I had been in past too! I also have many foreign wings including US, French and German and if I was a re-enactor could rightfully wear those wings on a period uniform too. I do not believe in wearing medals at all (period or ones rightfully earned)
I know it is important to get all of the detail right when showing a uniform especially for photos, displays etc but owners should point out to joe public that they are portraying a unit, person, type of uniform etc. This is similar to us making sure we get all the proper items and equipment to put onto (or hang off) our vehicles.
Just my tuppence worth
