Team a blue crew-neck sweater with chinos for an effortless kind of polish. You can follow the casual route in the shoe department by rocking white leather low top sneakers. If you frequently fret about dressing more maturely, this outfit is a fail-safe option.
This ensemble with a blue crew-neck sweater and chinos isn't a hard one to score and is easy to change according to circumstances. White low top sneakers will bring an easy-going vibe to an otherwise mostly dressed-up look. Overall, a great example of semi-casual fashion for 20-year-old gents.
