I am a big fan of layering especially in autumn/winter time.
Basic is a slim fit light jacket and I found denim jacket to be the best fit for the purpose.
Denim jacket could go under a jacket, coat or even thick cardigan (like shown on below photos).
On me: All saints thick wool cardigan, Lee denim jacket, levi's 510 skinny jeans, Knapp boots, Ray Ban Wayfarer sunglasses model 2140.
