This combo of a cardigan and grey chinos is on the off-duty side yet it's also on-trend and truly dapper. Bring a more laid-back aesthetic to by sporting blue canvas low top sneakers. You might be thinking that just because winter is colder you have to sacrifice on style, but that's just not true, and this outfit is a clear example. This is an outfit you, as a 30-year-old man, can always count on.
As you can see here, looking on-trend doesn't require that much effort. Just consider teaming a cardigan with grey chinos and you'll look incredibly stylish. Burgundy leather casual boots work spectacularly well within this look. As you can see here, this getup is hard proof that good style and dressing smartly for the colder months are not mutually exclusive. Seriously stylish, this getup is also absolutely age-appropriate for a 30-year-old.
