This relaxed casual combo of a long sleeve shirt and white shorts is a fail-safe option when you need to look casually stylish but have zero time to put together an ensemble. Tan boat shoes will never go out of style. Undoubtedly, it's easier to work through a warm weather day in a breezy look such as this one. Think 60-something guys can't pull off edgy casual looks? This pairing is irrefutable proof of otherwise.
