You'll be amazed at how super easy it is for any guy to get dressed like this. Just a brown crew-neck sweater worn with yellow chinos. You could perhaps get a bit experimental in the shoe department and throw a pair of grey canvas low top sneakers in the mix. As the temps start to drop, you'll see that a look like this is perfect for the season. This outfit demonstrates that passing the big 3-0 is no reason to avoid casual clothing.
