Pairing a navy shirt jacket with a light blue long sleeve shirt is a good option for an effortlessly sleek outfit. For something more on the sophisticated side to complement this outfit, complete your ensemble with a pair of navy velvet loafers. Needless to say, it's easier to work through an extremely hot hot weather afternoon in a light and breezy ensemble such as this one. Classic getups like this are worth having in your wardrobe no matter what age you are.
