This combination of a black shawl cardigan and charcoal chinos is proof that a pared down getup doesn't have to be boring. If you feel like dialing it up, complete this look with derby shoes. As the weather is getting warmer, it's time to get rid of those heavy winter layers and choose something lighter, like this look here. Men who are curious how to wear semi-casual looks as you go through your teen years, this combination should answer your question.
