This combination of a beige shirt jacket and navy jeans is outrageously stylish and yet it's casual and apt for anything. Introduce tan suede boat shoes to the equation to tie your full outfit together. So as you can see here, it's a kick-ass, not to mention spring-friendly, combination to keep in your seasonal sartorial collection. Perfect for a 20-year-old gent if you want to present an easy-going spirit.
