Yesterday we spoke about David Beckham's bangin' leather biker and today Justin Theroux is giving us yet more inspiration for autumn with this wool overcoat.

Traditionally the preserve of WWII spies and those men who stand on boxes at horse races, shouting out numbers, the wool overcoat is often overlooked when it comes to more casual attire.

But it doesn't have to be this way. As Theroux proves, if you combine a more formal overcoat with some relaxed attire – like a simple white T-shirt perhaps or a cotton Oxford shirt – all worn over a pair of skinny jeans and some simple boots or Vans Old Skool trainers, you have yourself a weekend-ready outfit that's cosy and cool. Aviators optional – but also, they're essential.
