Putting together a crew-neck sweater with olive chinos is a good pick for a casual yet on-trend outfit. Don't know how to finish? Complete this ensemble with white low top sneakers for a more laid-back finish. We highly recommend this one if you're on a mission for a winter-appropriate outfit that's as stylish as it is comfortable. This ensemble proves that as a 30-something Millennial man, you have a wide range of style options.
