Dude, in Power, Power Book II: Ghost, Empire, Succession, even in some K-dramas about wealthy people, they’re wearing designer stuff in every episode—even in their casual streetwear, hell, even their nightclothes! Is this unrealistic, or do rich people actually have ALL high-end designer clothes? Do some have shirts from Walmart or something?
They don’t have any reason to ever go to somewhere like Target or Forever 21. They only go into high end stores. Now they may occasionally see something in the high end stores that isn’t $400, but what anything costs is literally irrelevant to them. That’s assuming it’s the kind of wealthy person that even bothers to pick their own clothes versus having someone else do it.
