For a casual outfit with a modernized spin, you can easily opt for a white wool turtleneck and charcoal wool chinos. You could perhaps get a bit experimental when it comes to shoes and complement your outfit with a pair of dark brown leather casual boots. So if you're looking for an ensemble that's stylish but also totally season-appropriate, this one fits the bill. As a young gentleman, you want to start dressing like a grown-up. In this case, combinations like this come in useful.
