You'll be surprised at how easy it is for any man to throw together this casual outfit. Just a crew-neck sweater and sweatpants. Black leather loafers will bring a hint of polish to an otherwise everyday getup. As you can see, it's extremely easy to look sharp and stay toasty when chillier weather hits, all thanks to looks like this. Looking for dressing ideas for 20-somethings? This ensemble is pretty inspiring.
