The costuming in Succession is fascinating for what doesn't appear on the Roy family. On a different show, an uberrich family would be dressed dripping in Mentos-size diamonds, exotic furs, swinging Birkin bags, and the latest logo-laden collabs. But the Roy family are beyond that wardrobe. Above it, actually and literally, in their penthouses and high-rise boardrooms and helicopters looking down on the rest of us in their tasteful ensembles. The Roys are so rich, they don't have to flaunt it; they have nothing to prove. Their clothes are expensive, sure, but they don't need to posture with flashy logos or the latest-of-the-moment It item (think Jeff Bezos, Elon Musk, or other blandly dressed billionaires). There's a stratosphere of wealth that lives above the ostentatious.
The lesson: Less is more.
