For sharp menswear style without the need to sacrifice on comfort, we like this pairing of a tan turtleneck and navy jeans. If you want to easily smarten up your ensemble with one piece, why not complete your outfit with a pair of loafers? This one is a great pick when it comes to putting together a standout getup for in-between weather. As you see here, well into your 30s your styling options are pretty much limitless.
