Team a white and black dress shirt with a charcoal suit for a truly dapper outfit. Finishing off with chelsea boots is a guaranteed way to bring a mellow vibe to this outfit. So if it's a boiling hot hot weather afternoon and you want to look sharp without putting in too much work, this getup will do the job in next to no time. When it comes to style for 20-year-old gents, this look looks good on most men.
