This off-duty combination of a white short sleeve shirt and a navy denim shirt is very easy to pull together without a second thought, helping you look awesome and ready for anything without spending a ton of time digging through your closet. If you wish to immediately up the ante of this ensemble with a pair of shoes, complement this getup with a pair of tan suede derby shoes. If you're in your twenties, take cues from looks like this to take a more mature approach to your personal style.
