A zip neck sweater and a crew-neck t-shirt are absolute menswear essentials if you're planning an off-duty wardrobe that holds to the highest style standards. When in doubt about what to wear on the footwear front, slip into a pair of grey suede low top sneakers. This getup is a smart option when it comes to planning a well-coordinated ensemble for transitional weather. Perfect if you're scouting for some seriously inspiring casual style for 40-year-old guys.
