This combination of a cardigan and a beige short sleeve shirt will cement your expertise in menswear styling even on off-duty days. And if you need to easily dress down this ensemble with one item, complete this outfit with a pair of black and white canvas low top sneakers. When you have one of those dull fall days, sometimes only a cool outfit like this one can brighten it up. Definitely a foolproof option if we're talking style for adolescents.
