Putting together a beige shirt jacket with a white and black print crew-neck t-shirt is a great idea for a laid-back but seriously stylish look. Complement your outfit with white and red leather low top sneakers and ta-da: your outfit is complete. So as you can see, this look is a really nice choice, especially for transeasonal weather, when the temperatures are dropping. When it comes to casual style for 20-something gentlemen, this combination looks good on almost any man.
