This pairing of a blue dress shirt and a tan suit is a never-failing option when you need to look like a visionary in the men's style department. Kick up the wow factor of your outfit with a pair of brown leather chelsea boots. Needless to say, it's easier to work through an extremely hot summer day in a light and breezy combo like this. So if you need outfit ideas on what to wear as you pass the big three-oh, this combo is a wonderful example.
