Try pairing a grey shawl cardigan with dress pants to look smooth and sharp. To give this getup a more laid-back feel, add white canvas low top sneakers to this getup. As you can see here, this getup is a really smart choice, especially for awkward fall weather, when the temperature is getting lower. As you're heading into your 30s, you want to start dressing like a grown man. That's when looks like this are a surefire option.
