For a casually stylish look, wear a navy plaid shirt jacket with teal chinos — these items play beautifully together. Got bored with this outfit? Let a pair of white canvas low top sneakers switch things up. Keep this combo in your front hall wardrobe come spring, and we promise you'll save a lot of time planning an ensemble on more than one occasion. A no-brainer combination proper for 20-something gents who prefer casual clothing.
