For an ensemble that's worthy of a modern sartorially savvy gent and casually smart, wear a trenchcoat and grey chinos. Wondering how to finish? Introduce a pair of low top sneakers to the mix to shake things up. This one is a viable option when it comes to piecing together a kick-ass look for transitional weather. Ideal if you're on a mission for some seriously inspiring 20-something smart casual style.
