This laid-back pairing of an overcoat and navy sweatpants is a never-failing option when you need to look sharp but have no extra time to spare. Upgrade your look with navy and white suede low top sneakers. There's no better way to spice up a dreary fall day than an on-trend look like this one. When it comes to casualwear for 20-something gents, this getup looks cool on almost any guy.
