We're loving how this pairing of a tan waistcoat and khaki chinos instantly makes a man look sophisticated and dapper. As for shoes, complete your ensemble with a pair of brogues. When temps are getting lower and fall is setting in, you'll love this outfit as your favorite for summer-to-fall weather. As a 30-something Millennial gent, you probably want to start dressing like an adult. In this case, looks like this are perfect as inspo.
