This combination of a navy denim jacket and khaki jeans is hard proof that a straightforward off-duty look doesn't have to be boring. Introduce cowboy boots to the equation to make the ensemble less formal. This getup is a wonderful option come warmer weather.
Why not wear a navy denim jacket with beige jeans? As well as very practical, both of these items look awesome when teamed together. You could perhaps get a bit experimental on the shoe front and tone down your outfit by rounding off with cowboy boots. So as you can see here, it's a killer, not to mention spring-appropriate, getup to have in your transeasonal rotation.
