You'll be surprised at how extremely easy it is for any gent to get dressed this way. Just a navy suit and a navy turtleneck. Complement your outfit with a pair of dark green leather oxford shoes for an extra dose of style. So as you can see here, it's a kick-ass, not to mention spring-friendly, getup to keep in your transitional rotation. A good pairing to make you a dapper man over 40, rather than just a man over 40.
