This combo of a blue denim jacket and dress pants is a foolproof option when you need to look like a refined gentleman. Red high top sneakers will contrast beautifully against the rest of the look. Needless to say, it's easier to work through a hot summertime afternoon in a easy and breezy look like this one. As you move into your 30s, you want to start dressing like an adult man. That's when getups like this are a foolproof option.
