Team a navy vertical striped double breasted blazer with light blue ripped jeans for a relaxed look with a modern twist. You could go down a more casual route when it comes to footwear with white and blue leather high top sneakers. No doubt, it's easier to work through an extremely hot warm weather day in a breezy combo like this one. Casual ensembles for stylish guys in their thirties aren't actually that hard, as you can see here.
