Why dad needs it: Sorry, dads, but it's time to let go of those threadbare sweaters that still reek of the drugs you did in the '60s, '70s, and '80s. Don't worry, though. An ombre option will let your father showcase that he used to party back in the day (or currently) without sacrificing on style by holding on to what once was.
