Oh no! That sucks. Did Vestiaire catch that it's a fake or they sent it to you?
We have the Herbarium XL (the one with a jacquard exterior). It's a puddle of a bag, holds A LOT but because it's really only viable as a shoulder bag, you can't really carry that much without overloading your shoulder (carrying straps aren't exactly broad). I've carried a laptop and other work items in it once and it does fairly well. It almost feels like it would work better as a work bag if there was some internal organization, so we are thinking of getting a bag organizer for it. Quality-wise, it's impeccable, the leather parts of the bag are supple and lovely, and again a testament to the amazing leather and worksmanship of
Loewe.
