If you feel more confident wearing something practical, you'll like this on-trend pairing of a crew-neck t-shirt and white and navy shorts. Play down the classiness of this look by finishing off with white athletic shoes. Clearly, it's easier to work through a boiling hot hot weather afternoon in a easy and breezy getup like this one. Ideal to show the world that even as a teenage guy you can hold your own in the style department.
