To don a casual outfit with an edgy spin, make a crew-neck t-shirt and navy jeans your outfit choice. Kick up this whole getup by rounding off with a pair of brown leather chelsea boots. So so as you can see, it's a sharp, not to mention spring-ready, getup to keep in your seasonal rotation. As you go into your 30s, you probably want to start dressing like an adult man. That's when combos like this are a fail-safe option.
