This casual pairing of a turtleneck and navy sweatpants comes to rescue when you need to look good in a flash. You could perhaps get a bit experimental on the shoe front and dial down this look by slipping into a pair of black and white work boots. During winter, when warmth is a must, it can be easy to settle for a less-than-stylish look. But this look is a shining example that you can actually stay comfy and remain equally stylish during winter. This ensemble proves that reaching your 30s is no reason to stop dressing casually.
