For example, this dress is on sale as a used JH8962. I studied it, & I think it's a knockoff. The seller doesn't say that it is, but tell me what you think based on the real JH8962. http://www.recycledbride.com/listing/wedding-dresses/jim-hjelm-jh8962-2 I think it is based on how the ruffles look under the flash. They look gossamar and thin. Also it's being sold for $500. The real dress is thousands more. I haven't seen a bride yet sell a preowned dress for thousands at this low.
