Marry a white crew-neck t-shirt with grey ripped jeans if you're on the lookout for a look idea for when you want to look casually stylish. You can get a bit experimental in the footwear department and class up your ensemble by wearing a pair of brown leather double monks. No doubt, it's easier to work through a roasting hot warm weather day in a easy and breezy combo like this one. A good, less conservative outfit for a 30-something gent.
