For masculine refinement with a twist, consider wearing a mustard turtleneck and a navy suit. If you're hesitant about how to round off, a pair of brogues is a foolproof option. If you're already bored of your transitional season style options, this ensemble just might be the inspo you need. Perfect to show the world that even as a 20-year-old guy you're confident enough to hold your own in the sartorial department.
