This pairing of a camel duffle coat and khaki jeans couldn't possibly come across as anything other than ridiculously sharp and casually smart. And if you want to effortlessly smarten up your outfit with a pair of shoes, why not introduce dark brown leather derby shoes to the mix? During winter, when warmth is key, it can be easy to settle for a less-than-stylish ensemble in the name of functionality. However, this ensemble is a good illustration that you can actually stay comfortable and remain equally stylish in winter.
