A black and white shearling jacket and chinos paired together are the perfect ensemble for those dressers who love laid-back and cool combinations. Choose a pair of dark green athletic shoes to infuse an air of stylish effortlessness into your look. As you can see here, this combo is a really great pick, especially for transeasonal weather, when the temps are starting to drop. And if we're talking casual dressing ideas for mature men, this outfit is perfect.
