Why not pair a white polo with light blue chinos? As well as super comfortable, both items look nice together. A nice pair of teal athletic shoes is a simple way to punch up this look. You're sure to always look stylish even despite the scorching heat if you keep this outfit in your front hall closet.
Teaming a navy long sleeve shirt with light blue chinos is an on-point choice for a casual yet sharp look. Avoid looking too polished by finishing off with teal athletic shoes. Clearly, it's easier to work through a baking hot hot weather afternoon in a light and breezy outfit such as this one.
