One summer item that you never think is required but you need end up needing on multiple occasions is a navy blazer. It's one item that should always be available once wedding season rolls around, and throwing it on is the easiest way to add a touch of class and formality to an otherwise regular summer look. It pairs with nearly everything in your rotation, from polos to button downs, and from denim to lightweight chinos.
