For a look that looks as cool as it can get, rock an olive parka with a white crew-neck t-shirt. For something more on the dressier side to complete this getup, introduce navy and white canvas low top sneakers to the mix. Can you see how super easy it is to look sharp and stay warm when cooler weather hits, thanks to this ensemble? Wondering how to master casual dressing in your early 20s? This pairing is a great illustration.
