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?
No. I’ve tried, but I look completely out of place in designer anything.
EDIT: The truth is that designer clothes are typically a poorly constructed waste of money, unless appearances are everything, and your money needs to be “seen” to be made.
