I guess LV - Marc Jacbos do this awful over the top bags on purpose as a marketing strategy, they know they're not gonna sell many of those bags, and whether you like it or not, we're talking about that bag, same as every other magazine and fashion blog.
The same happened with Madonna's bunny ears at the Met Costume Gala, they trashed her in every single magazine and fashion blog in planet Earth! It was definetely the most talked about outfit of the night (maybe not in a good way) but everyone knew she wore Louis Vuitton from head to toe.
All press is good press!
