A blazer and a grey crew-neck sweater are the kind of a winning outfit that you need when you have no extra time. Go ahead and add dark brown leather low top sneakers to your look for a more casual feel. So if it's a baking hot summer day and you want to look on-trend without putting in too much work, this getup will do the job in next to no time. Laid-back ensembles for guys in their thirties aren't actually that hard, as you see here.
