A navy crew-neck t-shirt and grey sweatpants are a great combination to add to your off-duty styling arsenal. On the shoe front, go for something on the classier end of the spectrum with beige canvas low top sneakers. The practicality and simplicity of this outfit takes care of the heat and helps you make a ravishing statement wherever you go. Perfect to convey that even as a man in his twenties you're confident enough to hold your own in the outfit department.
