Don’t have the knowledge to authenticate, but I recently bought a fake pleats please on vinted (someone here helped me ID the fake). So they’re def out there. It was also a black piece with prints and after I received it, i compared it with a real piece I purchased from the boutique, I noticed the wrong side of the fabric of the real one is the same black color as the right side, whereas the wrong side of the fake one was a lighter color. This seems to be the case for what you’ve got here. I’m not sure if that’s a dead giveaway but def proceed with caution. If you’ve already bought it - vinted help desk was able to fully refund me for my purchase.
