Pair a grey puffer jacket with black chinos and you'll ooze rugged refinement and polish. For a more laid-back take, introduce white and black athletic shoes to your getup. On not so cold afternoons, you can sport this summer-to-autumn outfit and look absolutely amazing. All in all, a perfect example of casual style for 20-something gentlemen.
This combination of a grey puffer jacket and black chinos is hard proof that a pared down outfit can still be really smart. And if you wish to immediately dress down your outfit with a pair of shoes, complement your outfit with beige athletic shoes. Rest assured, this combo will keep you snug as well as looking seriously stylish in this weird transition weather. This ensemble demonstrates that as a 20-year-old gent, you have a wide range of style options.
