This is especially true with luxury brands like Louis Vuitton, Gucci, and Prada. People are either trying to impress others with fakes, or they’ve actually paid full price to become walking billboards.
Similar thing with iPhone cases that have a cutout for the Apple logo. That’s just hilarious.
At least an expensive car is usually a better product though, so many of these t-shirts are simply cheap cotton but the price is $$$$ because the logo of a company that also makes actually expensive products is on it.
