Marrying a navy print sweatshirt with navy jeans is a good option for a neat and relaxed getup. For a stylish hi/low mix, introduce a pair of beige suede desert boots to your ensemble. As the weather warms up, it's time to shed those heavy winter clothes and opt for something lighter, like this outfit here. As a 30-something gent, you want to start dressing like a grown man. In this case, ensembles like this are perfect as inspiration.
