For an outfit that's very simple but can be worn in a variety of different ways, wear a red shirt jacket and grey jeans. A good pair of beige leather low top sneakers is the most effective way to add a sense of stylish nonchalance to your look. It's a smart idea when it comes to figuring out a neat look for in-between weather. Those who are curious whether you can still sport modern casual outfits as you slip into your 40s, you have your answer.
