Layer up!
Living in Norway I know much more about this topic than I ever wished :-)
I know that layering is key when it comes to staying warm and dry but why not have some fun with it and be just a little bit edgy?
If you are getting bored with the usual sweater under your coat try something else underneath. A blazer, a leather jacket or maybe a denim jacket. Be creative!
I like to show off a denim jacket or my leather jacket under the oversized black coat. Just gives a little character or personality to my look. And the layers keep me warm.
