This off-duty combination of a multi colored horizontal striped crew-neck sweater and black leather chinos is extremely easy to pull together in no time, helping you look awesome and ready for anything without spending a ton of time rummaging through your wardrobe. For something more on the daring side to round off your outfit, complement this outfit with a pair of black leather work boots. This look is a pretty wonderful pick, especially for fall, when the temperature is dropping. A safe bet pairing appropriate for 20-year-old gents who like casual dressing.
