This casual combination of a light blue crew-neck t-shirt and navy corduroy chinos is capable of taking on different moods depending on the way you style it out. Why not add a pair of white athletic shoes to the equation for a more laid-back spin? A neat summer-to-fall ensemble like this one makes it super easy to welcome the new season. Ideal to tell people that even as a 20-year-old man you're confident enough to make your own style choices.
