This pairing of a blue crew-neck t-shirt and white shorts is undeniable proof that a pared down off-duty ensemble doesn't have to be boring. If you want to instantly ramp up this outfit with shoes, complete your outfit with boat shoes. No doubt, it's easier to work through an extremely hot warm weather afternoon in a cool outfit like this one. This getup is a great inspo to anyone who wasn't sure about sporting casual outfits as a 40-year-old man.
