I’m questioning this one. Mind you, I could be wrong, but I desired a Ballerine for years and scoured the internet for photos years ago.
Of the photos I’ve seen throughout the years, all have zippers and are made from a saffiano like leather that is very structured.
I don’t have a Vestiaire account, so I couldn’t see the bag’s details, but the bag looks quite warped, yet the ball henge looks right. About four or five years ago, the Ballerine cost at least $3500, so the original retail price on the Vestiaire Ballerine seems low.
I don’t know. I’m just giving my opinion. Best of luck.
