I, too, think it's suspicious that so many dresses turn up with sought after and valuable labels. Some of them are sewn in the wrong places, with the wrong thread - but labels do come off and are sewn back on. I always remove my good labels before they go to the dry cleaner because I've lost a few there.
Laura, sadly there are a few unethical sellers who see ebay/etsy as a get-rich-quick scheme and there is little that can be done to stop them. Best to trade with people that you trust. I recently emailed a seller because her dresses are always very, very short and I wondered at a 1940s mini dress but she replied that it was probably worn by a short lady and the hem was original. A very, very short lady!
This is also why I offer refunds to my customers, for any reason - I want them to be happy with their new dress. All of my vintage is authentic and I restore them as close as I can to original, taking down hems, moving buttons and taking out seams if it will not damage the garment. I'm in good company here at the VFG - we share a love for real vintage and treat it with respect.
These unethical, nay fraudulent sellers will never stop until the authorities speak to them. Even then, there is little to stop them trading under a new name. Buyer Beware! Shop VFG.
