As far as winter essentials go, you really can't go past the biker jacket. It's the kind of item that single-handedly can take even the most ho-hum of outfits and give it a painfully cool twist. I must admit, I am a new biker jacket gang member only having invested in one last year (Karl Lagerfeld from NET-A-PORTER, similar to the new-season version below) (such a name dropper!), but I tells ya what, I've no idea what the hell I was doing before it. I wrap myself up in its buttery soft leather on almost any occasion. I'm talking with evening stuff, trackies, jeans and prissy girly frocks. Yep, the leather jacket is pretty much the clothing version of that Ninja blender I've heard so much about - good at almost everything.
