A beige polo neck sweater and navy linen chinos are absolute staples if you're figuring out a classy wardrobe that matches up to the highest fashion standards. To introduce a bit of zing to this outfit, complement your ensemble with dark brown suede tassel loafers. So as you can see, this combination is a really nice idea, especially for transeasonal weather, when the temps are dipping. As a 30-something guy, you want to start dressing like an adult. That's when ensembles like this are a solid bet.
