I might have dreamt this, but I'm pretty sure there's a black and white photograph somewhere of Modernists, one of whom is wearing the dreaded aforementioned combination.  Is it, by any chance, in 'The Influential Factor'?  The book was once on sale at Russell Street.  Some kind of prize should be awarded to any poster identifying it.  I seem to remember him wearing a mac, too.  Even worse than the 'French Look' - but that was understandable in the context of wanting to convince your birds parents that your intentions were strictly honourable (or at least until they'd fixed the johnny machine down at the 'Dog And Duck').
Yes, a prize.
