The reason why people buy expensive, luxury brands is for two reasons. Because of the quality and because it makes a statement. When I put on my Gucci headband and walk out the door, I know I'm wearing it because I want people to see that I can afford Gucci (they don't need to know that I'm in tremendous credit card debt). Why do I do that? The answer is low self esteem, but the reason I want to focus on is that when I see other people wearing expensive brands, I know they have money.
That's why this tattoo is so stupid. Louis Vuitton is no doubt a luxury brand, but the name doesn't mean anything without the clothes. The same way you can't throw a Louis Vuitton logo on a Walmart shirt is the same way you can't just put Louis Vuitton on your skin. I bet this tattoo was cheaper than an actual long sleeve shirt at Louis Vuitton.
