Such pieces as an olive crew-neck sweater and light blue jeans are an easy way to introduce effortless cool into your day-to-day styling routine. For something more on the daring side to finish off your ensemble, introduce a pair of black and orange athletic shoes to the mix. Keep this outfit ready to go come spring, and we promise you'll save a ton of time getting ready on more than one morning. Overall, a perfect example of relaxed fashion for 20-something men.
