A navy wool shirt jacket looks so elegant when married with charcoal wool dress pants for a look worthy of a refined gent. Dial down your look by rounding off with a pair of white and navy canvas low top sneakers. As the weather improves, it's time to get rid of those heavy winter gear and opt for an ensemble that's lighter, like this one here. As a man in his 30s, you want to start dressing more like a mature gentleman. That's when inspiration like this is very useful.
