For an ensemble that's very easy but can be flaunted in plenty of different ways, marry a tan long sleeve shirt with a white crew-neck t-shirt. Feeling experimental today? Shake things up by wearing a pair of tan suede desert boots. So as you can see, it's a sharp, not to mention season-appropriate, look to keep in your transeasonal rotation. Casual combos for 20-something guys aren't actually that hard, as you see here.
