Pairing a dark brown pea coat and a long sleeve shirt is a guaranteed way to inject your wardrobe with some laid-back refinement. If you don't know how to round off, a pair of burgundy leather casual boots is a great choice. During the winter season, when warmth is the priority, it can be easy to surrender to a less-than-stylish look in the name of convenience. This look, however, is a bright example that you can actually stay comfortable and remain equally stylish in the winter season. Wondering what you should wear as you mature into your 30s? This getup is a perfect example.
