This is turning into a great discussion! I think it's a very valid point about the Hermes logo being so visible on a Birkin. I guess the Kelly shape has been copied by so many designers for so long that people don't know right away that it's Hermes since there is no visible logo. I wonder what would happen if I wore my Kellys with the flap tucked in so the logo shows??
Also, to many people all they know of the Kelly is that the Olsen twin(s) carry a very beat up thrift shop looking one- that presents a very different image than the rainbow of shiny new Birkins we see so many flashy celebrities and reality stars carrying.
I think it would be uncomfortable to wear the Kelly with the flap tucked in. I think I tried it once and realized it felt awkward given there is only one handle on the flap.
