The irony is the two most coveted bags in the world (the Birkin and Kelly) do not have giant HERMES printed on them. They are the ultimate splurge and yet my 68-year old dad wouldn't know if he was standing next to someone holding one. He wouldn't know the bag was from Hermes or that it was even designer, and certainly zero idea how much it costs. If he's standing next to someone carrying a Book Bag, yes, he will know it's from CHRISTIAN DIOR - not because he cares or is a fashion enthusiast in any way but simply because he can read it without his glasses.
When something has such an iconic design, you don't need to have giant logos and you don't need every toddler and grandpa to be able to read what brand it is. The people who know what a Birkin is just know. Just like they know when they see a Fendi Peekaboo. They can recognize a Givenchy Antigona or Saint Laurent Sac De Jour or Celine Belt Bag across 6 lane of traffic when there is no possible way of reading the small logo lettering from that far away.
I do agree at least some people feel that $4000 is not worth spending unless EVERYONE knows it's designer. They need their 6-year old cousin to be able to read CHRISTIAN DIOR loudly at a family lunch. They need people to read the giant CD from the small thumbnail on Instagram so they get more likes on their photo. And if my dad can't read the logo from across the street without glasses then they're just not getting bang for their buck!
