The sartorial arsenal of any discerning gent should always include such essentials as a light blue chambray long sleeve shirt and black dress pants. Give a dressed-down feel to this look by finishing with white low top sneakers. If it's one of those gloomy autumn days, what better to spice it up than a sharp outfit like this one? As you turn 30, you probably want to start dressing in a more refined manner. That's when looks like this are a surefire option.
