Why not choose a dark brown bomber jacket and jeans? As well as super practical, these two pieces look nice matched together. Feeling venturesome today? Shake up your ensemble by rounding off with dark brown leather loafers. So as you can see here, it's a knockout, not to mention spring-ready, getup to have in your transeasonal rotation. This getup is probably what you've been looking for as a gentleman in his 40s.
