The purpose behind this slightly pedestrian and admittedly cheapskate acquisition is twofold. (1) Because it was cheap I do not fear losing it - and having lost a favourite bespoke overcoat in a cloakroom I know what agony that can be. (2) It is – maybe next to a boiler suit – possibly the most effective prophylactic against the unavoidable and rather shocking dirt of public transport in the UK.
It did however get me thinking that the trench coat has rather fallen out of favour, and I'm slightly struggling to understand why this might be. I do remember they seemed to be somewhat more popular back in the 1970s (but then again so were safari suits, so that's no test of merit) and the Burberry – and latterly, Aquascutum – brands have taken off in a very peculiar commercial direction.
I think the origins of the trench coat are probably impeccable from a design point of view. I understand that they were originally intended, as the name suggests, to provide some kind of weather protection for the Poor Bloody Infantry manning the trenches in the Great War, and no doubt due their military origins often marked out a military veteran.

I can see that they are maybe slightly fussy for an entirely practical raincoat – but nevertheless I think they still demonstrate admirable practicality over mere decoration. And I can't imagine one would ever need to commission a bespoke one when the OTR versions are very adequate.
Is there any particular reason why they seem to have have fallen out of favour?
