Opt for a grey shawl cardigan and a light blue long sleeve shirt to pull together an interesting and modern-looking ensemble. And if you need to effortlessly dial down this ensemble with a pair of shoes, introduce brown leather work boots to this ensemble. This one is a nice option if you're crafting a well-coordinated look for transeasonal weather. Ideal if you're looking for some seriously inspiring off-duty style for 30-year-old guys.
