Effortlessly blurring the line between dapper and relaxed, this combination of a grey turtleneck and a crew-neck t-shirt will likely become your go-to. Complement your outfit with white canvas low top sneakers for maximum style. It's a viable option if you're planning a well-coordinated outfit for awkward fall weather. Just because you've hit your 40s, doesn't mean you're allowed to give up on your personal style, and this pairing illustrates exactly that.
