A grey crew-neck sweater and grey vertical striped chinos are indispensable menswear staples if you're crafting a casual wardrobe that holds to the highest style standards. Complete your look with black suede low top sneakers for extra style points. In winter, when warmth is key, it can be easy to surrender to a less-than-stylish ensemble. This ensemble, however, is a good illustration that you can actually stay snug and remain equally stylish during winter.
