Why not consider teaming a beige v-neck t-shirt with chinos? These pieces are totally comfortable and look nice when combined together. Dark brown velvet loafers are a surefire way to infuse a dash of sophistication into this ensemble. So as you can see here, it's a neat, not to mention spring-ready, look to have in your transeasonal rotation. Combinations like this have a refined air that suit gents in their 50s very well.
