Opt for a grey crew-neck t-shirt and shorts for a laid-back take on day-to-day menswear. White and black leather low top sneakers are a wonderful option to complete this outfit. When it's one of those dreary fall days, sometimes only a cool look like this one can get you out the door in the morning. Those who are curious how to pull off edgy casual looks as you mature into your 30s, you have your answer.
