This casual combo of a blue denim shirt and black chinos is a real lifesaver when you need to look neat and relaxed but have no extra time. For something more on the sophisticated side to complement your ensemble, introduce dark brown suede chelsea boots to the mix. In the winter months, when practicality is imperative, it can be easy to surrender to a less-than-stylish ensemble in the name of convenience. This ensemble, however, proves that you totally can stay toasty and remain equally stylish in the winter months. As a gent in his thirties, you probably want to start dressing maturely. In this case, combos like this are a solid bet.
