For a look that's super easy but can be smartened up or dressed down in a multitude of different ways, wear a dark brown blazer with light blue jeans. You could perhaps get a little creative in the footwear department and spruce up this look by finishing off with beige suede tassel loafers. You can bet this combination is great come blazing hot sunny days. This is a good-looking but also age-appropriate combo for 50-year-old men.
