No one will care if your spare tire is gleaming in the late-summer sunshine. No one will blink an eye if your body hair creates a halo around your creatively toned muscles. No one will give a flying fig if your sunglasses were purchased at a Taos gas station sometime during the hazy summer of 1981.
They won't care because YOU WON'T CARE, because you have the cojones to walk around wearing next-to-nothing and just not give a damn what anyone thinks. Because you're a man, and you enjoy it. And it's hot out.
Hey, whatever's comfortable.
