The versatility of a v-neck t-shirt and navy jeans guarantees they'll stay on regular rotation in your menswear arsenal. Take this ensemble a more sophisticated path by rounding off with a pair of brown desert boots. When it's one of those dreary fall days, sometimes only a cool look like this one can get you to face the outside world. If you often wonder how to dress as a 20-year-old gent, this ensemble is a vivid example.
