For an ensemble that's super simple but can be styled in a variety of different ways, go for a tobacco crew-neck sweater and a dress shirt. You could perhaps get a bit experimental in the shoe department and class up this look with dark brown leather brogues. When leaves are falling down and fall is in full swing, you'll love this ensemble as your favorite for unpredictable fall weather. This ensemble illustrates that as a 30-something guy, you have a wide range of styling options.
