Why not try pairing a navy harrington jacket with navy jeans? As well as super comfortable, both of these items look cool matched together. Our favorite of a multitude of ways to finish this outfit is a pair of white canvas low top sneakers. So as you can see here, it's an on-trend, not to mention spring-ready, combo to keep in your transeasonal rotation. This combo illustrates that well into your 30s you have a wide array of dressing options.
