A hoodie and beige chinos are absolute menswear must-haves if you're crafting an off-duty closet that holds to the highest fashion standards. For something more on the elegant end to finish off your getup, introduce a pair of black leather loafers to your getup. This is a never-failing option for an amazing transition ensemble. Stylish and age-appropriate for a 20-year-old man, an outfit like this will help outshine any of your pals.
