You'll be surprised at how super easy it is for any gentleman to get dressed like this. Just a shirt jacket paired with an olive zip sweater. If you don't want to go all out formal, introduce a pair of black and white canvas low top sneakers to your getup. As the weather begins to warm up again, it's time to get rid of those heavy winter layers and choose an ensemble that's lighter, like this one here. As a 30-something gent, you probably want to start dressing like a grown man. In this case, inspo like this comes in handy.
