If you're after a casual yet stylish outfit, make an olive shirt jacket and navy jeans your outfit choice. Rounding off with red canvas low top sneakers is a fail-safe way to add a playful feel to your look. As the weather starts to get warmer, it's time to get rid of those bulky winter layers and choose something lighter, like this look here. When it comes to casual dressing ideas for young men, this outfit looks great on almost anyone.
