This combination of a beige short sleeve shirt and a white and navy crew-neck t-shirt is extremely versatile and really apt for whatever the day throws at you. Complement this outfit with white canvas high top sneakers to keep the ensemble fresh. When it's one of those dreary autumn days, what better to brighten it up than a dapper ensemble like this one? Ideal to convey that even as a teenage guy you can hold your own in the style department.
