For a casually dapper outfit, consider wearing a teal crew-neck sweater and brown chinos — these pieces play really well together. And if you want to instantly up the ante of this ensemble with a pair of shoes, why not complete your getup with a pair of brown leather brogues? And if you're looking for a killer outfit that transitions easily into spring, this one fits the bill. As a gent in his thirties, you probably want to start dressing like a grown-up. That's when inspiration like this comes in useful.
