I really really really enjoy scarves. They keep me warm and the can do wonders with the most boring and dark winter coats, while some cost lest than a dollar. It is extremely easy to style a scarf, so just pick a colourful or one with a pattern with a dark coat, to give a bit of life to your look, or choose a dark one with interesting texture. If your clothes are very colourful, go with a dark or a biege one if you are not comfortable with mixing different prints.
Here is a bit of inspiration and some products I loved online:
