For effortless style without the need to sacrifice on practicality, we turn to this pairing of a mustard windbreaker and a grey print crew-neck t-shirt. Dark brown leather casual boots will instantly smarten up even the simplest outfit. This combo is a pretty wonderful idea, especially for autumn, when the temps are falling. This combination is a big inspiration to anyone who wasn't sure about sporting casual outfits as a 40-year-old guy.
