You'll be amazed at how easy it is for any gent to throw together this off-duty look. Just a navy crew-neck sweater worn with navy check chinos. Take this ensemble down a more laid-back path by sporting white leather high top sneakers. On not-so-bone-chilling afternoons, you can work this summer-to-fall outfit and look absolutely awesome. All in all, a good example of casual fashion for 20-year-old gentlemen.
