A dark green short sleeve shirt and charcoal jeans are the kind of a foolproof off-duty combo that you need when you have no time to assemble an outfit. A pair of white leather low top sneakers is a nice pick to complement your look. As we all know, the key to getting through the hottest time of year is wearing breezy looks like this one. When it comes to casual clothing for maturing gentlemen, this combo is perfect.
