For a casually smart look, consider teaming a navy trenchcoat with a light blue long sleeve shirt — these two pieces work nicely together. In the footwear department, go for something on the more elegant end of the spectrum and finish off your getup with a pair of brown leather derby shoes. Seeing as fall is taking over, this ensemble appears a viable option for the transitional season. As you're going from your 20s to your 30s, you want to start dressing like a grown man. If that's the case, getups like this are perfect as inspo.
