If you're scouting for an off-duty but also dapper ensemble, marry an overcoat with a charcoal crew-neck t-shirt. For something more on the cool and casual side to finish off this ensemble, enter a pair of charcoal print canvas high top sneakers into the equation. This ensemble is a really great idea, especially for fall, when the mercury is dipping. Those who are curious how to dress fashionably as you get into your 30s, you have your answer.
