Channel your inner James Bond and marry a navy suit with a grey turtleneck. When this outfit appears too dressy, dial it down by slipping into a pair of sneakers. So as you can see here, it's a neat, not to mention spring-friendly, combination to have in your seasonal closet. As you're moving through your adolescence, you probably want to look a little older than your age. In this case, inspiration like this comes in very handy.
