This casual combo of a dark brown print cardigan and white jeans is extremely easy to put together in next to no time, helping you look on-trend and prepared for anything without spending too much time digging through your wardrobe. Send an otherwise classic look in a more casual direction by finishing off with black leather work boots. Keep this getup in your head come spring, and rest assured, you'll save a ton of time racking your brain for a look on more than one occasion. If you often wonder how to dress as a guy in his twenties, this pairing is a practical example.
