A white and blue vertical striped dress shirt looks especially classy when matched with grey dress pants for an outfit worthy of a proper gentleman. Let your styling credentials really shine by rounding off this look with a pair of brown suede low top sneakers. No doubt, it's easier to work through an extremely hot day in a light and breezy combo such as this one. As you slip into your 30s, you probably want to start dressing more maturely. If that's the case, inspiration like this comes in very handy.
