This is hard proof that a grey turtleneck and navy chinos look awesome when combined together in a casual menswear style. Our favorite of a ton of ways to round off this outfit is with a pair of desert boots. Keep this look in your front hall wardrobe come warmer days, and we guarantee you'll save a lot of time planning what to wear on more than one morning. Perfect if you're looking for some amazingly inspiring style for 20-year-old gents.
