Team a navy wool blazer with white chinos if you're aiming for a proper, dapper getup. Inject a bit more edginess into this outfit by finishing off with a pair of black canvas high top sneakers. Can you see how very easy it is to look sharp and stay comfy when colder weather comes, thanks to this look? As a 30-year-old gentleman, you probably want to start dressing like a grown-up. In this case, getups like this are a never-failing option.
