This pairing of a white and violet harrington jacket and blue jeans is on the casual side yet it's also sharp and truly stylish. Our favorite of a countless number of ways to finish off this ensemble is with black and white canvas low top sneakers. This one is a viable pick if you're putting together a kick-ass summer-to-fall getup. Relaxed ensembles for 30-something men aren't actually that hard, as you can see.
