I didnt see this but hope to catch up with it later. I remember as a young PO in 1965 being in a group getting a pep talk on what was expected of an officer from an Air Commodore who told us we should always wear a clean collar every day. Obviously you missed that talk

I bought my first collar attached Van Heusen shirt in 1965 so I could wear it in shirt sleeve order, as the standard bib front shorts didnt have epaulettes for rank slides.
Uniform details on TV/films have got better over the years but obviously not quite right yet. Things have improved since the costume department on
