This combo of a black sweatshirt and a white crew-neck t-shirt is hard proof that a straightforward casual look doesn't have to be boring. To bring some extra depth to this outfit, introduce a pair of burgundy leather derby shoes to this ensemble. There's no nicer way to brighten up a dull fall day than an on-trend getup like this one. This ensemble is a great inspo to anyone who had doubts about wearing casual outfits as a mature gent.
