This off-duty combo of a tan barn jacket and light blue jeans is very easy to throw together without a second thought, helping you look awesome and ready for anything without spending a ton of time searching through your wardrobe. If you don't know how to round off, a pair of olive suede desert boots is a smart choice. This pairing proves that dressing appropriately for your age and looking fashionable are not mutually exclusive things for a 20-year-old gent.
