Putting together a double breasted blazer and a sweater vest is a fail-safe way to breathe style into your styling arsenal. For a more casual take, throw a pair of dark brown leather double monks into the mix. In the winter season, when warmth is crucial, it can be easy to surrender to a less-than-stylish ensemble in the name of convenience. But this ensemble is a stark illustration that you can actually stay cozy and remain stylish at the same time during the winter season. This ensemble illustrates that dressing stylishly as you slip into your 30s is not that daunting a task.
