A navy bomber jacket and khaki jeans are the kind of a no-brainer off-duty outfit that you need when you have no time to dress up. To give your overall outfit a more sophisticated feel, introduce a pair of navy suede casual boots to the mix. So so as you can see, it's a cool, not to mention spring-appropriate, getup to have in your transeasonal rotation. An outfit like this will make any 20-something gent look better than everyone else in the room.
