A white and navy vertical striped long sleeve shirt and charcoal jeans are must-have menswear must-haves to have in your casual box. Introduce a pair of beige suede tassel loafers to your outfit to take things up a notch. This one is an appealing option if you're crafting a knockout summer-to-fall ensemble. This is a combo you, as a 30-something man, can always count on.
