This combination of a v-neck sweater and grey sweatpants is very easy to throw together and so comfortable to sport as well! White and red low top sneakers are a foolproof footwear style that's also full of personality. During winter, when warmth is above all, it can be easy to settle for a less-than-stylish outfit. However, this outfit is a clear example that you totally can stay warm and remain equally stylish during winter. Ideal if you're on a mission for some incredibly inspiring casual style for men in their thirties.
