Jess Cartner-Morley reveal yourself 🧐 from the article, How to dress like a Parisian: big coats, monochrome and a splash of crimson (I disagree on the crimson/black combo though. Don't see that catching on in Paris at all evidenced by the fact that designers mentioned are not Parisian houses at all):
Selective quoting:
The Parisian thing was never about trends or dramatic reinventions. It has always been about an elegant line, a flattering colour, a charming detail; about a modern wardrobe of pieces that harmonise, rather than about standalone outfits and abrupt changes of direction.
...when a look is simple, the details are everything.
The shape you want in a coat or blazer is oversized, not baggy, so you need a strong shoulder.
Paris is championing vintage, at the highest level: archive Chanel is becoming a power move... (I think the fabulous JPG blazer you got is much more of a power move Elle, but I guess JC-M only stalks online)
Not many florals, and when they do turn up they tend to be the midnight-garden dark-floral variety.
