Please help authenticate this dress. I bought the lucina dress from Poshmark and received one with no Doen tag at the top of the item and a tag that says Made in Chine instead of China. Poshmark is insisting it is authentic and wants me to pay to have it authenticated for them to reopen the case. I will never buy off Poshmark again. I spoke with the seller who said she bought it off a website called LabelFetch, I have never heard of this site. I have emailed Doen to prove it is inauthentic but does anyone have any other suggestions or have been through this with Poshmark?
