A crew-neck sweater and light blue jeans are the kind of a fail-safe casual ensemble that you need when you have zero time. Our favorite of a variety of ways to complement this getup is a pair of blue leather boat shoes. So if you're on the lookout for a look that's stylish but also totally spring-friendly, this just might be it. As you can see, even in your fifties you still have a wide range of style options.
